Labour leader Jeremy Corbyn and other opposition party leaders have agreed a plan aimed at stopping the 'catastrophe' of a no deal Brexit.
And Mr Corbyn has agreed to put a halt to his original plan of installing himself as a caretaker Prime Minister following a vote of no confidence in Boris Johnson.
He has instead agreed with his fellow opposition leaders to focus on avoiding a no deal departure from the European Union on October 31.
Mr Corbyn had previously written to party leaders proposing that in the event of a vote of no confidence, he could be installed as a temporary Prime Minister before calling a General Election.
But after crunch talks today, this plan appears to have been put on ice - with the various parties now working together to find Parliamentary mechanisms that could stop a no deal.
Further talks will be held in the coming days ahead of the end of the summer recess next week.
A joint statement from Labour, SNP, Liberal Democrats, Plaid Cymru, the Green Party and the Independent Group for Change said the meetings were "productive and detailed".
The statement said: "Jeremy Corbyn outlined the legal advice he has received from Shadow Attorney General Shami Chakrabarti which calls Boris Johnson’s plans to suspend parliament to force through a No Deal "the gravest abuse of power and attack upon UK Constitutional principle in living memory".
"The attendees agreed that Boris Johnson has shown himself open to using anti-democratic means to force through no deal.
"The attendees agreed on the urgency to act together to find practical ways to prevent No Deal, including the possibility of passing legislation and a vote of no confidence."
Lib Dem leader Jo Swinson has told the BBC’s World at One programme that the meeting in Jeremy Corbyn’s office with other leaders trying to stop no-deal Brexit was “very positive”.
The outcome of the meeting sets the scene for a dramatic September in Parliament.
