John Bercow has defied his own pledge to quit as Speaker once again by vowing to stay over Brexit .
The Commons Speaker announced he is refusing to budge - despite now spending 10 years in office.
His decision is set to enrage Tory Brexiteers who believe he is trying to use his position to stop Brexit.
And it is could spark a constitutional crisis between Parliament and the new Tory Prime Minister.
Several leadership candidates including Boris Johnson, Dominic Raab and Esther McVey have said they'll make Brexit happen on October 31 - deal or no deal.
But Parliament has explicitly voted against No Deal.
And despite the top Tories insisting it's the legal default, Mr Bercow said in a US speech last night: "There is a difference between a legal default position and what the interplay of political forces in parliament will facilitate."
His comments threaten a fresh constitutional crisis of the kind that gripped Parliament earlier this year.
The Speaker scuppered Theresa May's bid to hold a third vote on her Brexit deal by saying she could not bring it back to Parliament in the same form.
Brexit Minister James Cleverly - the 11th Tory to enter the leadership race - insisted MPs' decision doesn't "take no deal off the table".
But he admitted "we've got to deal with the reality" that MPs have voted resoundingly against No Deal.
Tory leadership contender Jeremy Hunt, who has warned against No Deal, said: "Any responsible leader will have to reckon with this, whether we like it or not."
Fellow anti-No-Deal Tory leadership candidate Matt Hancock said the Speaker's announcement was "just confirming the inevitable".
He told the BBC: "It's a reflection of reality and we have to have a Brexit policy that's based on reality.
"It just shows that we need to deliver Brexit on a deal that can get through this Parliament, that is the only way to leave on 31st October which is very much what I want to do."
Mr Bercow famously declared he would serve only for nine years when he first took the Speaker's chair on 22 June 2009.
Since then he has breached his pledge, prompting aborted no confidence attempts by Tory MPs.
But despite friends telling newspapers he would resign this summer, a year late, he's now said he intends to stay on even longer.
He told The Guardian: "I’ve never said anything about going in July of this year.
"Secondly, I do feel that now is a time in which momentous events are taking place and there are great issues to be resolved and in those circumstances, it doesn’t seem to me sensible to vacate the chair."
He added: "If I had any intention to announce on that matter … I would do so to parliament first."
