Former Chancellor Philip Hammond has accused the PM of trying to wreck the chance of a new Brexit deal, by making demands the EU could never accept.
In a Times article, Mr Hammond said a no-deal Brexit would be “a betrayal” of the 2016 referendum result.
He said Parliament would “make its voice heard”, adding that a no deal “must not happen”.
A No 10 source said the UK would leave on 31 October despite Hammond’s “best efforts to the contrary”.
The source added that Mr Hammond, as chancellor, “did everything he could” to block preparations for leaving and had “undermined negotiations”.
In the meantime, The Commons speaker John Bercow slammed the suggestion Boris Johnson could shut parliament, vowing to “fight it with every bone in my body”.
In his first public comments since the new prime minister won the keys to Number 10, the Daily Telegraph said Bercow also went one step further and claimed the Commons could stop Britain leaving the EU without a withdrawal agreement on 31 October.
The option of suspending parliament – known as “proroguing” it – was raised when Sky News reported that Johnson’s team were considering it during the Tory leadership race.
It sparked a fierce backlash from opponents who said they would challenge the move in the courts, including former Conservative prime minister Sir John Major.
