Anna Soubry, who leads the Independent Group of Change - which has 5 MPs - also categorically ruled out supporting a Corbyn-led temporary government.
It continued with Philip Hammond, the former Chancellor and prominent Remainer, threatening to vote against his own government in any motion of no confidence.
"Jo Swinson has been stating the obvious" in that "if you want to get a vote of no confidence, you have to have a different candidate for Prime Minister".
"At the same time we have always said that we're also preparing for the possibility of an exit without a deal, which we don't want and which is viewed very negatively".
"The principle is that the Labour Party is the main opposition party, we've an aspiration to go into government.We are ready to serve", he told the BBC.
Moreover, there has been a separate sect of Conservative MPs who have proposed the idea of an interim Government to take over from Mr Johnson.

This could be tricky, because the Government controls the parliamentary timetable and there are limited chances for the opposition to introduce legislation.

Mr Clarke also said: "A government of national unity is just one of the things that might be called for".
"And I'm confident that if that's what the House of Commons resolves that those individuals will be happy to take on that role to try to steer our country through these hard waters".
Ms Swinson is coming under increasing pressure to back Mr Corbyn's suggestion, which includes forcing out Boris Johnson in a vote of no confidence and securing an extension to the Brexit deadline beyond October 31. "He was prepared to say anything in his selfish quest to become Prime Minister at all costs". "The UK will definitely be leaving the European Union on Oct 31st - it is in our mutual interest to do so with a Deal, but we will be ready to leave with No Deal".
But chances are that egos and political divisions will prove too much, the unlikely coalition will fail, the "Voice of the People" will go unheard, and Johnson will lead the United Kingdom into a most uncertain future.
She praised Ms Wollaston, who represents Totnes, as a "formidable" MP and said: "I am so glad to have her by my side in our fight to stop Brexit".
"To stop him, everyone who cares about democracy, our country and our future must work together because there are enough of us - from all parties in Parliament - to stop him".
She added that she "suspected" it would be called "within days" but declined to give a specific day.
Several Labour figures believe the plan could gain a majority in the Commons.
