Labor MPs were asked to prepare for Jeremy Corbyn's dramatic and immediate vote of no confidence against Theresa May's government on Tuesday evening to force general elections if she suffered a major defeat this week, as expected United Kingdom and Gibraltar European Union membership referendum deal.
Messages were sent to Labor MEPs (including those who did not feel well) to ensure that they were present on both the Tuesday and the following day for "meaningful voting" in the Prime Minister's Brexit Plan. The whips of the Labor Party have informed MEPs that the vote of no confidence will likely be submitted within hours of a government loss. The actual vote will take place on Wednesday.
The news comes before what promises to be one of the most turbulent 24 hours in recent parliamentary history, in which May, subject to a renewed delay, its Brexit deal despite heavy and widespread opposition throughout the House of Commons, including many MPs within its own Parliament, Parliament will present a party.
A senior Shadow Cabinet member said, "It is now recognized that we can not wait any longer. If May is defeated and she does not resign and does not call for an election, we have to act now. "
Senior Tories said on Saturday that they could not see how the Prime Minister could win the meaningful vote "at all costs" and that a defeat of less than 100 would now be considered the best they could hope for.
But even if she suffered a loss of nearly 200 that many Tories might fear, Conservative MPs and ministers expect her to continue to waver and try to bring an improved offer to the House of Commons for further votes within weeks.
Although the leading Labor members have agreed that they are unlikely to win a vote of no confidence, as the ten Democratic Union MPs have said they will support the government, the move will face the fragility of May's power in power the Brexit crisis.
Should Corbyn fail to force a vote, it will put pressure on the Labor leader, many of his own MPs, and party members and supporters to put his weight behind a second referendum to break Brexit's impasse.
Labor's current policy is to force an election and, if it wins, renegotiate a new Brexit deal. According to senior Shadow Cabinet officials, a further delay in filing a motion of censure would make that position unsustainable as there is not enough time to make a choice until the UK leaves the EU on 29 March.
The Observer is aware that if Corbyn delayed the postponement of a motion of censure, Labor MPs themselves would submit themselves in the hope of forcing the leadership to support a second referendum. Angela Smith, Labor MP for Penistone and Stocksbridge, said: "The time for the spread of violence is over. If May's deal fails, we must test the will of the House, and if we fail, we must consider all options, including the campaign for a second referendum, as this is party politics. "
Although a Labor Party spokesman did not confirm a vote on Tuesday, he said that the date for a vote of no confidence had not been fixed, but MEPs were ready to be ready. Barry Gardiner, the shadow trade minister, said last week that a vote of no-confidence should "obviously" follow immediately after a defeat for May's deal.
A momentum activist, Michael Chessum, spokesman for the left-wing anti-Brexit campaign "Another Europe is Possible," said that if Labor won the vote of confidence, it would be time for Corbyn to hold a second referendum as part of the Labor Manifesto to support. If it has lost, it should work as an official opposition to one.
He said, "Proposing a motion of censure is the first step in both scenarios, and we need to continue with it." Labor activists for a second referendum claim that the party's policy forum had received more than 13,000 emails and letters asking Corbyn to oppose Brexit.
Sadiq Khan, Mayor of Labor, said he would step up his campaign for another referendum if an election is not called immediately: "A public vote would not only allow us to go beyond the current stalemate, but actually begin much-needed Process of healing the deep divisions that have opened in our society. "
Roy Hattersley, the seasoned Labor politician, made a second referendum on Saturday and said the British people have "a right to decide on the merits" of May.
In the meantime, the ministers who remain in the Cabinet are preparing to push for a softer Brexit this week. In the event of a defeat in May, they can support a Plan B that would prevent Britain from signing its own trade agreements.
Some believe that joining a permanent customs union with the EU could be enough to get a majority of the commons for the May deal. This could be an option proposed in a series of preliminary votes to examine MEPs' views on alternatives if their plan is rejected. Such a move could possibly attract a bloc of Labor MPs.
Tory rebels are already planning a series of measures in a critical week to give Parliament more power over Brexit. A high-ranking person stated that a "legal copper bottom" plan had already been drawn up to "give Parliament control of Brexit and stop a no-deal Brexit" if May's deal is rejected.
A poll showing that there is a commons majority for a Brexit delay is also planned by a bipartisan group of deputies. "If we do not crash and do not seek the prime minister's deal, I can not believe that Article 50 does not need to be expanded," said one of the participants.
Economics Minister Greg Clark, who also wrote in the Observer, called on the pro-Brexit Labor MPs to support the May Agreement, insisting that the government would protect workers' rights if the UK is outside the EU. He promised to support an amendment proposed by the MPs on this subject.
