Mr Johnson's Foreign Secretary Dominic Raab has claimed the Tories have the numbers to get the Brexit deal through Parliament.
Mr Johnson seemed to have the support of French President Emmanuel Macron, who said that a Brexit delay would be "in the interest of no one".
If passed, it would force the Prime Minister to ask Brussels for an extension to the 31 October deadline until every piece of legislation needed to make Brexit happen has passed through the Commons.
This stage of Brexit was supposed to definitely be the endgame, but the can-kicked-down-the-road reality was more like the Avengers franchise, splitting the final story into yet another two parts.
The Prime Minister told the Commons that the Brexit issue must not be allowed to "consume" Westminster any more.
Described Boris Johnson's three-letter strategy as "childish".
Pro-European Union MPs are considering supporting a customs union amendment to the government's Brexit bill in order to dilute it ahead of a second referendum.
DUP Brexit spokesman Sammy Wilson said they supported the so-called Letwin amendment "as the only avenue available to properly scrutinise the deal on offer and attempt to secure changes that could address some of the concerns we have".
Tusk said he had received the request from Johnson.
Footage posted to social media showed both Mrs Leadsom and her Cabinet colleagues Jacob Rees-Mogg and Michael Gove being heckled by People's Vote demonstrators as they left the House of Parliament under police escort.
During angry scenes in the first Commons Saturday sitting since the 1982 Falklands War, Mr Corbyn demanded that the Prime Minister should "obey the law" and ask the European Union for an extension.
It should have failed because Prime Minister Johnson managed to secure a last-minute agreement with the European Union last week only by breaking his promise to Northern Ireland that he would never agree to put a border in the Irish Sea, thereby separating it from the rest of the United Kingdom.
Former minister Amber Rudd said she and most of the 21 Conservatives kicked out of the ruling party over their bid to block a no-deal Brexit would support the deal and there was "a fragile but honest coalition of people who want to support it".
Peter Bone claimed a second Brexit referendum would be "something to look at" if it was a choice between Boris Johnson's deal and no deal. "I will support it, I will vote for it", Letwin told BBC television.
