Iain Duncan Smith has warned of remain parties forming an anti-Brexit government if Boris Johnson were to lose a snap election.
The former Conservative Party leader said it was "wholly possible" that Britain could be led by a remain-supporting coalition.
"If there was a vote of confidence and the government lost, you’re then in the hands of all of those who voted against – remember they’re almost all remainers," he told talkRADIO's Julia Hartley-Brewer.
“They might just decide to form a government for a few months, just to stop us leaving – it’s wholly possible that these conniving so-and-so’s would actually do that.”
This weekend, it was reported that the People’s Vote campaign was calling for its supporters to vote tactically in the event of a snap election to snag some 100 marginal seats from pro-Brexit MPs.
And in last week's Brecon and Radnorshire by-election, the Green Party and Plaid Cymru both stood aside to ensure a remain party victory in the form of the Liberal Democrats.
The Lib Dem win brought Boris Johnson's working parliamentary majority down to just one.
Newly-elected Liberal Democrat leader Jo Swinson has been vocal about her party's anti-Brexit stance, and called on Labour leader Jeremy Corbyn to stop “aiding and abetting this Conservative Brexit” and table a motion of no-confidence against Boris Johnson’s government in order to trigger an election.
And party member Chuka Umunna has openly supported the idea of a remain alliance.
He told talkRADIO: "You are looking at the remain parties, the Liberal Democrats, Plaid Cymru, the SNP and the other small groups, and the Green Party of course.
"I do not see how you could have Conservative or Labour candidates included in that, because they will be carrying a whip which is not a remain whip."
However, Mr Duncan Smith added that he “absolutely believes” the Conservative Party would win a vote of confidence if it came to it.
