Boris Johnson, the former foreign secretary, attacked Prime Minister Theresa May's "dithering" over Brexit negotiation, dismissing her plan as "enforced vassalage" as the United Kingdom remains under some European Union rules.
In an article for The Mail on Sunday, she called for MPs to take a "practical and pragmatic" approach rather than face a "damaging and disorderly" Brexit.
She tweeted: "Govt are running scared and using silly tactics to avoid plotting by their own MPs". The pro-leave Tory MP Andrea Jenkyns, a vehement critic of the Chequers proposal, asked: "Could the prime minister inform the house at what point it was decided that Brexit means remain?"
Plaid Cymru, who have rejected deals with the Conservatives in the Welsh Assembly, said if stopping a "hard Brexit" required them to enter an all-party government "so be it".
A group of pro-EU Conservative MPs supported a measure that would have changed the government's post-Brexit trade strategy. The founder of BeLeave, Darren Grimes, was fined 20,000 pounds and referred to the police, along with a Vote Leave official, David Halsall.
Resignation statements like Mr Johnson's have previously been used by former ministers to inflict a departing blow on prime ministers with whom they have clashed.
'Had we not won we would have been looking at even more letters, ' one said.
Under the Fixed Term Parliaments Act, it would then be possible for a government made up of MPs from all parties that support a sensible resolution, to come together under the banner of staying within the Single Market and the Customs Union.
Tory grandee Sir Nicholas Soames tweeted: "I don't think in my 35 years as an MP that I have ever known such a truly unpleasant and deeply uncertain time in the House #soverydifficulttoseeawayaheadsorrytowhingebutitstrue".
Corbyn denied he had been misleading: "I stated the fact that the Electoral Commission has made that reference".
He used a Daily Telegraph column to ominously say "I will resist - for now - the temptation to bang on about Brexit". That is a guarantee they will cooperate.
His resignation followed a Cabinet summit at which ministers agreed to follow May's plan to pursue a softer form of Brexit which would keep the United Kingdom aligned with European Union regulations on key issues.
May's plans for exiting the European Union were narrowly approved by the House of Commons in a series of votes this week, but only after she bowed to Brexit hardliners led by Jacob Rees-Mogg to salvage her program.
Corbyn ended with his by now traditional summing up of his arguments, which are packaged as social media clips by Labour and shared widely.
Speaker John Bercow intervened as Tory MPs tried to shout down the Labour leader.
Steve Baker, who also quit as a Brexit minister, urged her to step up preparations for a "no deal" scenario. "The only way forward is put this issue to the public and have a People's Vote on the final Brexit deal".
"Now that there is collective agreement to accelerate delivery of our plans, will she please give instructions that every communication related to no deal serves to bolster our negotiating position and by reinforcing the credibility and the feasibility of those contingency plans?"
