Update 10: After trending steadily lower ahead of the vote, the pound roared into the green as the Commons adjourned for the day, as traders realized that analysts who had warned about a spectacular defeat of May's deal being good for the pound may have been on to something.

With hundreds of Labour MPs preparing to pivot toward a second referendum this week, it appears more of Jeremy Corbyn's positions are being foisted upon May as she scrambles to figure out what's next for her deal.

And even May's own cabinet is expected to pressure her to change course and advocate for staying within the customs union - something that is anathema to hard Brexiteers.

What will Theresa May do next?



Government sources say she will now come under 'huge pressure' to tack to a Customs Union - both from within her Cabinet and and without. — Steven Swinford (@Steven_Swinford) January 15, 2019

And in a potential threat to the pound and May's government, Labour has indicated that it will try again if it loses the no confidence vote against May tomorrow.

New:



Labour indicates it will try again if it fails to win the confidence vote tomorrow.



So just as PM went into meaningful vote today knowing she would lose, so Labour will go into confidence vote tomorrow expecting defeat.



Plus ça change



🤷‍♂️ — Steven Swinford (@Steven_Swinford) January 15, 2019

If May loses the vote, Labour has made clear that all options - including a second referendum - are on the table.

And even if she wins, May and the EU have now gotten the message loud and clear: May's deal is unworkable. If the EU refuses to compromise, a no deal Brexit is also clearly not going to work, since Parliament last week adopted an amendment to make sure such an outcome would require its explicit authorization.

At this point, a delay of Article 50 is looking extremely likely, unless May can win some serious concessions from the EU. But all the bloc needs to do now is dig in its heels and refuse to budge on the deal, and there will suddenly be a strong possibility that Brexit will be killed.

Though one currency strategist for TD Bank argued that it's tough to get excited about the pound since the situation is so uncertain.

"While we have bounced since, we struggle to get excited about sterling’s upside here," said Ned Rumpeltin, European head of FX strategy at Toronto-Dominion Bank. "We could see some market participants begin to think that the next move will be in favor of a ‘No Brexit’ outcome, but there is still a lot of blue water between here and there."

But one thing is for sure. If there is a Brexit, it could be even softer than the deal currently on the table, as May said after the vote that May would begin cross-party talks - possibly including Labour Jeremy Corbyn - later this week, though Corbyn was quick to reject the offer in his statement.

Despite Tuesday's surge in optimism about the possibility that Brexit could be foiled, the pound remains 15% below its pre-Brexit level. And according to a group of economists polled by Bloomberg, the best-case scenario would be another poll on whether Britain should leave the EU, which would boost the currency to $1.35. The worst case would be leaving with no deal , which could see the pound drop to $1.15.

As we noted in the tweet below from European Council President Donald Tusk, the EU27 isn't thrilled about the outcome of the vote. Soon, we may see more bureaucrats hinting non-too-subtly that maybe its time for the UK to rethink the whole Brexit process, democracy be damned.

Update 9: The House has adjourned for the day, and cable has continued its ascent toward the $1.2850 level.

* * *

Update 8: Steve Baker, director of the Brexiteer faction in the European Research Group, has met with May to lay out what is presumably their preferred alternative to May's Brexit plan.

A temporary free-trade agreement only about the movement of goods, which wouldn’t need the ratification of the EU’s 27 members A temporary zero tariff on some imports from the EU in order to keep food prices down The U.K. could withhold some or all of its 39 billion-pound annual contribution, as it is not in an implementation period May’s government could force the measure through by secondary legislation to an existing act of Parliament or amend future legislation

Meanwhile, amid the chaos in the aftermath of Tuesday's vote, this quote reportedly used by Winston Churchill to mock Americans is once again being thrown around to mock the fractiousness in May's conservative party.

"You can always count on them to do the right thing - after they have tried everything else."

A reporter for one German newspaper, citing several EU27 sources, said they would support delaying Brexit Day until the end of June (though a recent ECJ decision granted the EU unilateral authority to do so).

* * *

Update 7: In a silver lining for May, the DUP has said it will back May in Wednesday's no confidence vote, meaning that the only way for the opposition to topple the government would be for a number of Tory rebels to side with Labour which is...unlikely.

* * *

Update 6: Comment from European leaders are starting to break on twitter, with the Austrian PM insisting that, though the defeat of the deal is unfortunate, there won't be a renegotiation of the deal.

In one of the more aggressive comments, Donald Tusk seemed to imply that, if the deal is so unpopular, maybe the UK should reconsider this whole Brexit thing.

If a deal is impossible, and no one wants no deal, then who will finally have the courage to say what the only positive solution is? — Donald Tusk (@eucopresident) January 15, 2019

The pound has broken above $1.28.

Update 5: The pound kneejerked lower, but swiftly recovered as traders realized that the overwhelming defeat means the EU may now reconsider its decision not to reopen negotiations.

It's now up on the day.

May said in a speech that "we must focus on ideas that are genuinely negotiable." She also denied that the government's strategy is to run down the clock.

Before officially tabling his motion of no confidence, Jeremy Corbyn called for a permanent customs union, saying a permanent customs union must be secured, after gloating over the worst defeat for a government since the 1920s. No deal must be taken off the table and people's rights and protections must be secured.

"I inform you Mr. Speaker I have now tabled a motion of no confidence in this government and I'm pleased that motion will be debated tomorrow so this House can give its verdict on the sheer incompetence of this government."

* * *

Update 4: May has lost by a 230 vote margin. As the results were read out, the Commons erupted in commotion.

The final results: 432-202

The pound is puking.

* * *

Update 3: Minutes before the final results are due, reporters have noted that the 'no' lobby is mobbed. "It's safe to say May's deal is sunk", one commented.

Word is the government only has 202 votes - which would mean a sizable defeat. That would be 475 against, an overwhelming rejection that would bring her ability to schedule another vote into question.

Though that's nothing we didn't already know.

Update 2: The Baron amendment has been rejected by a vote of 24-600. The amendment would have called for the UK to have the ability to unilaterally leave the backstop.

Amendment (f) results in:

NO 600

The rejection of the amendment, which May opposed, is a resounding win for the prime minister. Cable has caught a slight bid on the news.

Stocks legged lower after the Brexit headline hit, which could be a sign that algos read "reject" in the headline and reflexively dumped.

Update: The voting has just begun but there's already been a handful of surprises. Three of the four accepted amendments have been dropped, so voting will proceed on the final amendment (the Baron amendment, backed by a cross-party group of legislators) before proceeding directly to the motion to pass.

317 is the magic number needed for the motion to pass.

Bloomberg now expects the final tally to arrive by 2:30 pm ET. Cable is flat as voting begins.

After months of fractious negotiations during which Theresa May has repeatedly tried - and failed - to win over intransigent Tories and members of the small Northern Irish party upon which she depends for her tenuous Parliamentary majority, May's supremely unpopular Brexit withdrawal deal is finally coming up for a vote in the House of Commons.

Almost nobody, including May herself, expects it to pass. In fact, most analysts expect the deal to be defeated by a wide margin of at least 150 votes, which would be tantamount to the worst defeat for a British government in 95 years, according to Bloomberg.

At least 70 members of May's party have publicly pledged to oppose the deal, and members of the Brexiteer European Research Group have also vowed to vote down each of the four proposed amendments that MPs will be decided before the deal comes up for a vote.

The debate and the votes will be broadcast live from Westminster following a speech from May. Readers can watch the action below:

May has just over two months to secure a withdrawal agreement palatable to both Parliament and the EU27 leaders, or risk a delay of Article 50 - which would push back the Brexit deadline - or possibly a chaotic 'no deal' outcome (though Parliament has recently taken steps to ensure that a 'no deal' exit would require the explicit approval of Parliament). UK diplomats are reportedly already working under the assumption that the March 29 "Brexit Day" will likely be delayed.

Per the Wall Street Journal, four amendments to the motion to pass the deal have been selected by John Bercow, the Speaker of the House of Commons, including one that would exclude a no-deal Brexit and another that would put a time limit on the UK's transition out of the EU. Another amendment, which May has said isn't palatable to Brexiteers (or the EU) is the Leigh amendment, which would put a time limit on the backstop.

Bad news for Downing Street



John Bercow has selected FOUR amendments:

NOT Murrison or Swire — Steven Swinford (@Steven_Swinford) January 15, 2019

In theory, the amendments would give May, Parliament and the EU a better idea of what Parliament would accept. May is expected to return to Brussels within 48 hours of Tuesday's vote to meet with EU leaders, who have recently signaled that they might be open to making some minor changes to the deal. But a stunning defeat in Parliament is seen as an essential step before this can happen.

Shortly before the vote was scheduled to begin, headlines crossed the wires reporting that May would return with an even better Brexit deal next week (an amendment passed last week requires May to return with a 'Plan B' within a few days of the deal's defeat).

The latest reports suggest that May's efforts to convince some Tories to abstain instead of voting against the deal have been ineffective, which suggests the deal likely will lose by a sizable margin. Labour has confirmed that it will be voting against the deal. Party leader Jeremy Corbyn has also threatened to table a motion of no-confidence in May's government if she loses the vote, saying that Labour would seek another general election.

As analysts try to suss out what the vote could mean for the pound, a team from Capital Economics said that an inconclusive moderate defeat could be the worst outcome because it would increase uncertainty by taking away some incentives for May and the EU to compromise. A narrow defeat of only 50 votes could send sterling higher, perhaps above $1.30, while a miracle victory for May could send the pound all the way to $1.40.

Meanwhile, cable slipped under $1.27 as traders waited for the votes to begin (currency traders have weighed in with various takes on what they believe could happen to the pound).

CE published a table of odds for various outcomes, putting a heavy defeat at the highest likelihood with 53%>

Given the confusion around the arcane Commons rules being invoked to push through the amendments, the House of Commons twitter account has published a handy guide to how the voting will proceed.

How will voting on amendments work this evening?

After announcing his provisional selection of amendments, the Speaker explained the process and we've turned it into a diagram to make it easier to understand.



Watch the Speaker's explanation: https://t.co/fX3LdU4isW #BrexitVote pic.twitter.com/DFP5bsR4s3 — UK House of Commons (@HouseofCommons) January 15, 2019

Looking beyond Tuesday's vote, Deutsche Bank tabulated the odds for various Brexit outcomes. Ultimately, a loss of 150 votes or more could increase the chances that May resigns or is pushed out following the vote (text courtesy of Deutsche Bank).

A) May resignation/withdrawal of cabinet support: 20% probability. While we think this unlikely, there is a chance Prime Minister May resigns following the vote, particularly should the government's loss be toward the top end of the scale mentioned above. Another possibility is the cabinet collectively withdraw support, making her position untenable. The main reason why we see this as unlikely is that under Conservative Party rules, unless MPs can agree on a single candidate to replace the Prime Minister, a leadership contest would follow. As Conservative MPs will find it difficult to agree on a single replacement candidate, unless Prime Minister May chooses to resign, we think the cabinet will seek to avoid a de-stabilising leadership contest. Should May resign and a leadership contest materialise, we would anticipate a pro Brexit candidate to be successful. 1While this would increase the likelihood of a no deal Brexit, our base case would be that new elections result, particularly if government policy pivots towards no deal.

B) May remains as leader: 80% probability. The government will then have to provide an updated Brexit strategy to parliament by Monday 21st January. In these circumstances, we see five corresponding scenarios, in order of least to most disruptive.

1) A cross party consensus: 30% probability. Having lost the vote, Prime Minister May pivots towards a cross party approach to EU negotiations or parliament agrees an alternative negotiating mandate and instructs the government to follow it at the next vote on the 21st January or subsequently. For a cross party compromise to be reached, we think it may be necessary for the Labour Party to call, and lose, a vote of no confidence in the government first. We envisage a new mandate would instruct the government to renegotiate the Political Declaration on the Future Relationship towards a softer future relationship. 2 In conjunct with firmer EU commitments linking the Withdrawal Agreement and Political Declaration on the Future Relationship, such a deal should probably carry majority support in parliament. A small (two to four weeks) extension of Article 50 becomes necessary, as well as another round of EU negotiations. We envisage the EU27 would be flexible on both extending Article 50 and reopening talks on the future relationship. This is the most positive scenario, with markets being able to forecast an orderly outcome with a relatively high degree of confidence.

2) A lack of alternatives: 10% probability. Parliamentary consensus does not emerge on the next steps by the vote on the 21st January, or subsequently. Prime Minister May then uses multiple votes to force the existing deal through parliament in the face of a crash Brexit, perhaps after some cosmetic changes to the existing Withdrawal Agreement, and likely with market pressure. Again an extension of Article 50 from the EU27 becomes necessary. This is a more bearish scenario in that it may require market pressure or downside economic risks materialising for MPs to agree.

3) A second referendum: 15% probability. The government's policy switches to seeking a second Brexit referendum, or (more likely) MPs direct the government to call one at the vote on the 21st January or subsequently. Article 50 is extended to July, or perhaps beyond. We have slightly increased the probability of a second referendum following reports over the last few days the EU27 could envisage an extension of Article 50 beyond the EU Parliament elections in late May, and perhaps well beyond when MEPs take their seats in July. We still believe a bigger sticking point to a second Brexit vote is that while parliamentary consensus could emerge to hold one, consensus on the question asked of the electorate will be more difficult.

4) A new election: 15% probability. May loses the vote and the Labour Party calls a successful confidence motion in the government. After two weeks, assuming a new government cannot be formed, a new election would follow under the Fixed Term Parliament Act. In this scenario, again an extension of Article 50 would be required. We do not see this as a positive scenario in that polls indicate both major parties are close to tied, leading to the risk of an election leading to similar parliamentary gridlock as at present. For a no confidence motion to be successful, the government will have to formally lose the support of the DUP, or a similar number of Conservative MPs from either the extreme pro Brexit or soft Brexit wings of the party.

5) A no deal/crash Brexit: 10% probability. Political deadlock leads to no deal Brexit. This could materialise if a parliamentary consensus does not emerge on an alternative deal, or Prime Minister May fails to get the current Withdrawal Agreement through parliament after multiple times of asking, and a motion of no confidence in the government is unsuccessful.

Scenarios not discussed:

May winning tomorrow's vote. While we had attached a probability of 40% to May securing political support for the Withdrawal Agreement last week, this was contingent on May pivoting towards a cross party approach in the meantime, which has not materialised. We now do not think there is a realistic probability of the government winning tomorrow's vote.

Revocation of A50. Following a ruling from the ECJ, it is now technically possible for the UK to unilaterally revoke the Article 50 process (the UK's exit from the EU). Revoking Article 50 would carry an enormously high political price, however, and we do not see it as likely at this stage.

* * *

Amid all of the chaos ahead of the vote, there are really only two outcomes that most analysts agree on. May will almost certainly lose on Tuesday, and Brexit Day will almost certainly be delayed as May and the EU finally begin work on a modified deal that might have a chance of passing Parliament.
