Lawmakers will be asked to approve a statement setting out the option to have a short delay by agreeing to a Brexit deal by March 20 or a longer delay if no deal can be agreed in time.

Parliament is not voting at this stage to choose which option Britain should take.

The vote comes a day after parliament rejected Britain leaving the EU without a deal after chaotic scenes when May’s government struggled to exert any authority over her divided Conservative Party.

Voting is due to begin at 1700 GMT and parliament will try again to wrest control of Brexit from the government by submitting alternative proposals, known as amendments, to the government’s statement which will be voted on.

The speaker has selected four main amendments to be voted on. If any pass, they will either alter the wording of the government statement or replace it entirely. If all the amendments fail, the government proposal will be voted upon last.

Below are the details of the government motion and the key amendments proposed by lawmakers. The governing Conservative Party has reportedly told its lawmakers oppose all the amendments.

GOVERNMENT MOTION

This will form the basis of the debate and says three things:

1) Notes parliament has rejected May’s deal and a no-deal scenario, and agrees the government will seek an extension to the Brexit negotiating period, which currently ends on March 29.

2) Parliament agrees that if lawmakers approve a divorce deal by March 20, the government will seek to agree “a one-off extension” until June 30 to pass legislation needed to smooth Britain’s departure from the EU.

3) Parliament notes if it has not approved a divorce deal by March 20, then it is “highly likely that the European Council at its meeting the following day would require a clear purpose for any extension, not least to determine its length, and that any extension beyond 30 June 2019 would require the United Kingdom to hold European Parliament elections in May 2019”.

AMENDMENT H: SECOND REFERENDUM

Led by Independent Group lawmaker Sarah Wollaston, and with support from members of several different parties have submitted an amendment which, if passed, would instruct the government to request a delay to Brexit to allow time to hold a second referendum.

AMENDMENT I: FIND ANOTHER WAY

Led by lawmaker Hilary Benn, a cross-party group have put forward a proposal which would take control of the parliamentary agenda on March 20 with the aim of forcing a discussion of Brexit options at a later date.

This process, which would overturn the usual rule that the government controls what is discussed in parliament, is aimed at trying to find a majority for an alternative Brexit path that would break the parliamentary deadlock.

AMENDMENT E: DIFFERENT APPROACH

Jeremy Corbyn’s opposition Labour Party has submitted an amendment calling for May to use a Brexit delay to give parliament time “to find a majority for a different approach”.

AMENDMENT J: NO MORE BREXIT VOTES

This amendment, submitted by Labour lawmaker Chris Bryant, seeks to prohibit the government from asking parliament to vote on May’s exit deal for a third time, citing parliamentary convention that the same question should not be asked of lawmakers more than once.
