Labour MPs are being urged to back a plan to keep the UK in a Norway-style relationship with the EU, as MPs debate Brexit’s next steps.
MPs will vote later to see if any proposals can win a majority – after failing to secure majorities last week.
Under the Common Market 2.0 proposal, the UK would leave the EU, but retain freedom of movement and make contributions to the EU Budget.
The Speaker has selected four motions, including one on a customs union.
International Trade Secretary Liam Fox told the BBC joining a customs union would be a “betrayal of Brexit”.
The SNP are also proposing to back the Common Market 2.0 motion, put forward by Tory MP Nick Boles.
But the PM’s spokesman said ending free movement was a “very important factor” for the public when voting for Brexit, so they would oppose it.
Shadow foreign secretary Emily Thornberry, speaking to the BBC’s World at One programme, refused to say whether Labour’s position on free movement had changed.
When asked if she was compromising on freedom of movement, she said “we are trying to pull the House of Commons together”.
Conservative MPs are being given a free vote on the motions – meaning they will not be told by party bosses which way to go – but the cabinet has been told to abstain.
None of today’s votes on the proposals are legally binding, meaning it will be up to the government if they act on the results.
Theresa May tried to get MPs to back the withdrawal agreement element of her deal on Friday, but lost by 58 votes – having already failed twice to get support for her overall deal in Parliament.
She now has until 12 April to either seek a longer extension to the deadline or decide to leave the EU without a deal.
The cabinet is now split over whether to move to a softer deal that could mean including a customs union in her plan.
Chief whip’s criticism
It comes as the Tory Chief Whip criticised the government for not making it clear the UK would “inevitably” have to accept a closer relationship with the EU after Brexit.
Julian Smith told a BBC documentary that after his party failed to get a majority in the 2017 election, “the government as a whole probably should have just been clearer on the consequences of that”.
In interviews for The Brexit Storm: Laura Kuenssberg’s Inside Story, he also accused ministers of trying to undermine the prime minister.
Mr Smith said he witnessed them “sitting around the cabinet table… trying to destabilise her [Mrs May]” and described their behaviour as the “worst example of ill-discipline in cabinet in British political history”.
How will the day work?
The Commons started with MPs debating and voting on a business motion that laid out plans for the votes later and set aside time for any next steps on Wednesday.
It was approved by 322 votes to 277.
The Speaker John Bercow then decided which motions to take forward for MPs to vote on tonight.
He picked four of the eight put forward:
- Motion C: Committing the government to negotiating “a permanent and comprehensive UK-wide customs union with the EU” as part of any Brexit deal – proposed by Tory former chancellor Ken Clarke
- Motion D: Referred to as Common Market 2.0, this option would mean joining the European Free Trade Association and European Economic Area – proposed by Tory MP Nick Boles
- Motion E: This is for a confirmatory referendum, giving the public a vote to approve any Brexit deal passed by Parliament before it can be implemented – proposed by Labour MPs Peter Kyle and Phil Wilson
- Motion G: The motion aims to prevent the UK leaving without a deal, including a vote on whether to revoke Article 50 – stopping Brexit – if the EU does not agree to an extension – proposed by the SNP’s Joanna Cherry
He did not choose motions calling for a unilateral exit to the backstop, to leave on 12 April without a deal, to hold a referendum in the case of no-deal or to rejoin the European Free Trade Association.
MPs are now debating the proposals until 20:00 BST, after which – as with the indicative votes last week – MPs will be given a piece of paper listing all the options and tick “yes” or “no” on as many as they want.
The House will be suspended for 30 minutes to allow the votes to take place. It took two hours for the votes to be counted before, so the result could be around 22:00 BST.
Will any of the options get a majority?
When MPs voted on proposals last week, all eight failed to win a majority in the Commons.
However, the plan for a customs union – allowing UK businesses to move goods around the EU without tariffs, but stopping the UK striking independent trade deals – and a confirmatory referendum came the closest.
A number of cabinet ministers have spoken out against the proposal.
Mr Fox said that if the UK pursued a customs union, it would have to follow rules set by the EU, adding: “It’s time we went back to a proper Brexit.”
Environment Secretary Michael Gove said agreeing a customs union would “compromise” pledges the party made in their 2017 manifesto, while Defence Secretary Gavin Williamson said ministers were “determined” to avoid that happening.
Meanwhile, Tory MP Huw Merriman has written to around 200 of his colleagues who have voted in favour of Mrs May’s deal, appealing for them to back the confirmatory referendum motion to prevent the customs union option succeeding.
He said: “It is the only option which keeps the [PM’s] deal alive and is not contingent on more EU negotiations.”
Digital Minister Margot James also told BBC Two’s Politics Live that she is thinking about changing her mind to back a confirmatory referendum.
What happens next?
- Wednesday 3 April: Potentially another round of so-called “indicative votes”
- Wednesday 10 April: Emergency summit of EU leaders to consider any UK request for further extension
- Friday 12 April: Brexit day, if UK does not seek/EU does not grant further delay
- 23-26 May: European Parliamentary elections
