The group including leading Tory, Labour and Liberal Democrat MPs, are confident of taking control of Parliament and preventing Theresa May’s successor from pursuing a no deal Brexit. Yvette Cooper, Nick Boles and Sir Oliver Letwin are prominent figures in the group, who are plotting a series of measures to ensure the next Prime Minister cannot railroad Britain out of the EU without an agreement on October 31. Leading contenders in the Tory leadership contest including as Boris Johnson, Dominic Raab and Esther McVey have already signalled their intention to leave the EU, deal or no deal, once the deadline is reached.
However the powerful group of Europhiles has warned the hardline Brexiteers, they risk being the shortest reigning Prime Minister in history if they press ahead with their plan.
One Tory MP told The Sunday Times: “We are now confident we have the numbers to bring down any new Prime Minister who tries to pursue no deal Brexit.
“It could be the shortest-ever tenure of any Prime Minister in history.”
With the European Union unwilling to re-negotiate Mrs May’s withdrawal agreement, which was defeated three times in the House of Commons, it is unclear whether MPs will even get another deal to vote on.
Before the original March 29 exit day, MPs turned parliament on its head, after a bill proposed by Ms Cooper was passed and forced the Prime Minister to extend Article 50.
Mr Boles, who resigned from the Tory party in defiance over its stance on Brexit, states this avenue may not be available but was “cautiously optimistic” there is another way.
He said: “We have been working on it. The route we used before is not available, but we are cautiously optimistic that we will be able to find another.”
Meanwhile a senior Labour source said: “As parliament has shown before, where there is a will in parliament to stop no deal a way will be found.
“The new Prime Minister should be left in absolutely no doubt that we will not allow no deal to happen.”
Whilst a Lib Dem source added: “All I can confirm is that these discussions are happening and we are involved.”
Earlier this week, Commons Speaker John Bercow reassured MPs they would be involved in the Brexit process after he dismissed any suggestion parliament could be shut down to force through no deal.
Mr Bercow said: “Parliament will not be evacuated from the centre stage of the decision-making process on this important matter. That’s simply not going to happen.”
