PM battles to keep Brexit plan on track after Amber Rudd quit the government on Saturday

Boris Johnson will fly to Dublin to meet the Irish prime minister, Leo Varadkar, on Monday, as he battles to show that his Brexit plan remains on track after Amber Rudd dramatically quit the cabinet.

Against a backdrop of mounting disquiet inside government at Johnson’s gung-ho approach and the combative style of his chief strategist Dominic Cummings, the British prime minister hopes to demonstrate that he is serious about negotiating a fresh Brexit deal.

When he returns from Dublin later on Monday, Johnson is expected to make a second bid to trigger a 15 October general election by asking MPs to support a motion tabled under the Fixed-term Parliaments Act.

But he is almost certain to be rebuffed for a second time, after opposition leaders agreed on Friday to reject a snap poll until a no-deal Brexit has been definitively avoided. The backbench bill aimed at blocking no deal is expected to receive royal assent on Monday.

Rudd’s abrupt departure followed that of the prime minister’s brother, Jo Johnson, who resigned last week after 21 rebels lost the Conservative whip for supporting what Downing Street calls “Jeremy Corbyn’s surrender bill”.

Rudd’s resignation on Saturday evening sparked fears of a domino effect, with other Tory moderates following suit.

Since tendering her resignation, Rudd has been approached by three cabinet ministers and nine junior ministers who have expressed concern about the direction of the government, a friend said, adding that she would not be at all surprised if there were more resignations.

Her final conversation with the PM took place on Saturday evening, when she called him 10 minutes before an article revealing her resignation was due to be launched online. An agitated Johnson pleaded with her to reconsider.

“The PM wanted to know why she hadn’t told him first. But it is obvious why and she told him: ‘Boris, you have some pretty brutal advisers,’” a Rudd aide said.

Downing Street launched a shoring-up operation, with Johnson himself speaking to key potential waverers. Cabinet ministers known to have anxieties, including Matt Hancock, Julian Smith and Robert Buckland, made clear on Sunday they intended to remain in the government.

Hancock has been lobbying for the whip to be restored to the rebels, according to friends, while Buckland, the justice secretary, tweeted that he had spoken to the prime minister “regarding the importance of the Rule of Law, which I as Lord Chancellor have taken an oath to uphold”.

Robert Buckland QC MP (@RobertBuckland) Speculation about my future is wide of the mark. I fully support the Prime Minister and will continue to serve in his Cabinet. We have spoken over the past 24 hours regarding the importance of the Rule of Law, which I as Lord Chancellor have taken an oath to uphold.

Johnson has insisted he would rather be “dead in a ditch” than delay Brexit, as the backbench law passed last week would oblige him to do if he has not agreed a deal that can pass through parliament by 19 October.

On Sunday, Dominic Raab, the foreign secretary, was asked how the government intended to proceed. He appeared to suggest Downing Street would seek to find some way around the legislation.

“We will adhere to the law but also this is such a bad piece of legislation … we will also want to test to the limit what it does actually lawfully require. We will look very carefully at the implications and our interpretation of it,” he told Sky’s Sophy Ridge on Sunday.

One idea under consideration is that the government could append additional material to the letter requesting an extension to article 50 mandated in the legislation.

A Downing Street source said Johnson could seek to “sabotage” any extension. “The ‘surrender bill’ only kicks in if an extension is offered. Once people realise our plans there is a good chance we won’t be offered a delay. Even if we are, we intend to sabotage that too.”

The crossbench rebel alliance that drafted the bill have left what they believe will be sufficient time between 19 October and Brexit day at the end of the month for the government to be challenged in the courts if it refuses to act.

The alliance will make a renewed bid to seize control of the parliamentary timetable on Monday, in the hope of forcing the government to publish its assessment of the risks of a no-deal Brexit.

However, No 10 remains convinced that outside the Westminster bubble, voters will see Johnson as determinedly trying to deliver Brexit in the face of a cantankerous political establishment.

“It feels like we’re suffering body blow after body blow in Westminster, but they’re really resolute about the whole thing,” said one senior Tory.

Former justice secretary David Gauke warned last week that moderate voters would be repelled by what he called a “Farage-lite” approach.

But another government insider said they had been reassured by Downing Street in recent days that private polling shows even voters in constituencies where moderate Conservative MPs have been chucked out of the party in recent days are being won over by the message of increased funds for the NHS and schools.

In Dublin on Monday, Johnson will be under pressure to spell out more details of how his government intends to replace what he has called the “anti-democratic” backstop for the Irish border.

He has suggested an all-Ireland system of sanitary and phytosanitary (SPS) checks on agricultural products might provide part of the solution – but Varadkar has pointed out such issues only account for about 30% of border checks.

“It’s not enough on its own. We would need a single Irish economic zone, or whatever you would like to call it, to cover more than agriculture and food,” Varadkar said on Friday.

That approach would be anathema to the Democratic Unionist party. It was its members objection to border checks in the Irish Sea that helped push Theresa May towards reworking the backstop to cover the UK as a whole.

Varadkar and his deputy, Simon Coveney, have spent the last two days stressing the backstop is about normal life on the border, as well as trade in agriculture and other goods.

During a tour of no-deal inspection posts at Dublin’s docks on Sunday, Varadkar said he did not expect a “breakthrough” tomorrow at his first face-to-face meeting with Johnson but all efforts would remain focussed on a deal. He added that “the stakes are high”.

The shadow Brexit secretary, Keir Starmer, warned the government against going back on the detailed commitments May made in the 2017 December agreement to protect the integrity of the Good Friday agreement.

He said: “Over recent weeks, there have been disturbing briefings coming out of government about its intention to backtrack on the solemn commitments made to the people of Northern Ireland two years ago.

“Those commitments were the foundation of an agreement with the EU that would protect the peace process and avoid a hard border in Northern Ireland. When Boris Johnson meets the Irish prime minister, he must make absolutely clear there will be no rowing back and the government will not take the negotiations down such a reckless path.”

Plaid Cymru’s Westminster leader, Liz Saville Roberts, suggested on Monday that the PM could be impeached – an arcane parliamentary procedure Johnson himself once suggested could be used to compel Tony Blair to explain his decision to go to war in Iraq.

“Boris Johnson has already driven a bulldozer through the constitution, so no longer are ideas like impeachment farfetched,” said Saville Roberts. “I will tell other opposition party leaders, we need to be ready to impeach Boris Johnson if he breaks the law.”
