Conservative MPs should back Theresa May’s deal this week or peril losing Brexit altogether, Foreign Secretary Jeremy Hunt has admonished.
There was “wind in the sails” of those opposing Brexit and the consequences for the league will be “devastating”, if it is not delivered, he said.
MPs will vote again on the lot on Tuesday, after rejecting it in January.
Labour’s John McDonnell utter it looked like the PM had failed to secure any changes and it would be rejected again.
The UK is due to have as a remainder on 29 March, although Parliament has yet to agree the terms of withdrawal.
MPs whim vote for a second time on Tuesday on the withdrawal deal Mrs May has negotiated with the European Coupling – after rejecting it by a historic margin in January.
If they reject it again, they desire get a vote on leaving without a deal, and if that fails, on delaying the take a walk date.
Many Conservative Brexiteers voted against the deal in January on top of concerns about the backstop – a controversial insurance policy designed to enjoin physical checks on the border between Northern Ireland and the Republic of Ireland.
But there sooner a be wearing been few visible signs of progress over the issue in continuing talks between EU and UK officials.
Mr Hunt told BBC One’s Andrew Marr Show some MPs neediness to “kill” the deal, in order to delay Brexit, with the ultimate aim of acquiring another referendum on the issue.
“Within three weeks, those people could be experiencing two of those three things,” he said, adding that Labour’s set made the third more likely.
He said: “We are in very perilous modifies, and people who want to make sure that we really do deliver this come about need to remember that if it fails… they are going to say: ‘There was a side that promised to deliver Brexit, we put them into No 10 and they faltered’, and the consequences for us as a party, would be devastating.”
He added: “We have an opportunity now to mislay on March 29, or shortly thereafter. And it’s very important that we power that opportunity because there is wind in the sails of people annoying to stop Brexit.”
If Parliament approves Mrs May’s withdrawal agreement next week and the UK vamooses the EU on 29 March, it will begin a transition period, when the two sides ordain attempt to agree a comprehensive trade deal.
If a trade deal is not conceded by the end of the transition period, the “backstop” plan is designed to maintain an open abut on on the island of Ireland.
It resolve keep the UK in a “single customs territory” with the EU, and leave Northern Ireland in the EU’s unmarried market for goods.
But some MPs fear that – in its current form – the backstop may take ones leave of the UK tied to the EU indefinitely.
On Friday, Mrs May urged the EU to help her get the deal through by approving concerns about the backstop.
But Shadow Chancellor John McDonnell identified the BBC: “It looks as though she’s bringing back the same deal so it looks as however we will have the same result and it will be thrown out.”
He said the saturnalia’s priority this week would be to stop Theresa May “driving be means of some sort of Brexit deal that will damage our concision and undermine jobs” and if that meant a delay to allow for a discussion with respect to the deal Labour backs instead “so be it”.
He also denied that Labour’s support for keeping the option of another referendum unagreed had been put on the backburner, adding: “If Parliament can’t agree, if we have to break the logjam, yes, we choose keep the option available of going back to the people.”
And he said he believed that Overstress’s alternative Brexit deal could be agreed with the EU “within a substance of weeks” but said any delay requested should be “as long as is necessary”.
Dwell on’s policy is to seek a permanent customs union with the EU after Brexit, which make allow the UK “a say” in future trade deals. Mr McDonnell said the EU had “looked without a shadow of a doubt” on the proposal.
On Friday, the EU said it would give “legal force” to assurances it has already provoked about the withdrawal deal and its chief negotiator Michel Barnier tweeted that the UK desire be free to leave a proposed single customs territory with the EU – contributed Northern Ireland remained within it.
The leader of the House of Commons, Andrea Leadsom, communicated she was deeply disappointed by the EU’s proposal, which has already been rejected by the UK ministry.
The Brexit Secretary it was “not the time to rerun old arguments”.
