The UK could be heading for another general election if MPs back a bid to block a no-deal Brexit on Tuesday.
Addressing the nation during a speech outside 10 Downing Street, Prime Minister Boris Johnson insisted "I don't want an election, you don't want an election".
But he said he would not seek an extension to the Brexit deadline - which is what a cross-party alliance are demanding if there is not a deal.
A senior Government source said Mr Johnson would request a general election on October 14 if MPs back the cross-party move to seize control of Commons business on Tuesday.
A motion for the early election will be tabled by the Government which would require the support of two-thirds of MPs under the provisions of the Fixed-term Parliaments Act.
The Government source said MPs will face a "simple choice" tomorrow.
The source said the vote would be treated as though it is a vote of no confidence, and that any Conservative MP voting against the Government would have the whip removed from them.
The source said: "If they vote tomorrow to wreck the negotiation process, to go against giving Britain the ability to negotiate a deal, then they'll also have to reflect on what comes next."
Chris Leslie, MP for Nottingham East said in his newsletter: "Anything that dissolves Parliament at this crucial stage will amplify the risks of a no-deal occurring, because it is only by having legislators in place in the Commons that we can restrain the powers of Boris Johnson as Prime Minister.
"If an election is called now, Boris remains as Prime Minister throughout – with executive powers to change the date of that election and potentially see the UK crash-out with no-deal. He would have free reign and nothing would be able to stand in his way.
"Consequently, I am not in favour of dissolving Parliament at this stage – especially as this Prime Minister cannot be trusted to keep any promises made - and I will do whatever I can to protect Nottingham’s jobs, livelihoods and public services from the hurricane of a no-deal Brexit.
"Events will be fast moving each day this week. Brexit needs to be dealt with first and separated from a cut-and-run election, where Johnson will seek to capitalise on Corbyn’s poll ratings. With so little time left before October 31 the key task is for a coalition across the parties to put the national interest first."
MP for Broxtowe Anna Soubry took to Twitter to say: "Any MP who votes for a General Election is voting for a No Deal Brexit.
"The priority must be to pass legislation to stop no deal and that’s what MPs of all parties are determined to do."
