The amendment, which will be put to a vote on Thursday, would force the Government to come back to Parliament by the end of the month to hold a substantive vote in the Commons on its plan for Brexit. It sets a clear deadline for when MPs can have a say on what happens next in the Brexit process, either through a meaningful vote or an amendable motion. Mr Corbyn said: “This amendment would stop the Government from running down the clock on the Brexit negotiations, hoping Members of Parliament can be blackmailed into supporting a botched deal.
“This is an act of gross irresponsibility.
“The Prime Minister is playing for time and playing with people’s jobs, our economic security and the future of our industry.
“This week Parliament should set a clear deadline for the Government to come forward with its revised deal or give MPs the chance to decide what happens next.”
In heated exchanges in Parliament earlier today, Mr Corbyn accused Mrs May of trying to “blackmail people into supporting a flawed deal”.
He argued the only possible way to avoid a hard border was to stay in a customs union with the EU, claiming Mrs May’s deal did not offer the same benefits.
Mrs May responded: “He talked about uncertainty, of course the best way to end uncertainties is to vote for a deal.
“He talked about running down the clock, no, I wanted to have this sorted before Christmas, I brought back a deal before Christmas.
“Every time you vote against a deal the risk of a no-deal Brexit is raised.”
Mrs May also set out plans to “short circuit” parliamentary rules in order to get her deal ratified in time for the UK to leave the EU on March 29.
She told MPs that she would enable the House of Commons to lift a requirement for a 21-day delay before any vote to approve an international treaty.
She said: ”In most circumstances, that period may be important in order for this House to have an opportunity to study that agreement.
“But of course, in this instance MPs will already have debated and approved the agreement as part of the meaningful vote.
“So while we will follow normal procedure if we can, where there is insufficient time remaining following a successful meaningful vote, we will make provision in the Withdrawal Agreement Bill – with Parliament’s consent – to ensure that we are able to ratify on time to guarantee our exit in an orderly way.”
Her announcement came as she urged MPs to “hold their nerve” and support her efforts to secure a withdrawal deal which will deliver on time.
In a statement updating the Commons on progress in talks, Mrs May acknowledged she would need “some time” to seek legally-binding changes from the EU to the controversial backstop for the Irish border.
Labour’s amendment states: “Leave out from “House” to end and add “requires by 27 February 2019 a Minister of the Crown either (a) to move another motion under Section 13(1)(b) of the European Union (Withdrawal) Act 2018 or (b) to make a written statement declaring that there is no longer an agreement in principle in the negotiations with the European Union and to move by that date an amendable motion on how the Government proposes to proceed.”
