Sending to the LBC radio, Ann Widdecombe said the conservatives would be "crazy" to continue rejecting an electoral alliance with the Brexit party, leaving seats represented by the remaining deputies. She said, "We're running out of time, and we'll be closing in next week, and that's all in Boris's camp, not in Nigel's camp.
"By occupying seats, while I say that they would not vote for Tory, and if the Conservatives are stupid enough to divide the votes on those seats, well, it's up to them to decide.
"That's exactly what happened in Peterborough and Brecon." In the Peterborough by-election, we arrived at hundreds, only a few hundred wins, the Conservatives got a few thousands of voices but failed, now if we had a few thousand votes, we would have done well, we would have won.
"And the same thing is true in Britain, the Conservatives have come together, we've got a few thousand votes, but we've been left behind, and now if they could have our votes, would have won.
"That's the kind of pact we're talking about."

But his appeal comes as the Brexiteers invite Nigel Farage to withdraw the candidates of the Brexit Party in the next elections in December.
The Brexit leader has been warned that his party could split the permission vote and block Britain's departure from the European Union.
A former candidate urges his colleagues to abstain or risk depriving Boris Johnson of the majority on December 12 and to reinforce the "hideous" prospect of helping Jeremy Corbyn to rank number 10.
Philip Walling, who retired from the battle for Workington headquarters in Cumbria, said: "I beg all the other Brexit candidates to do what I did: examine your conscience in the light of reason.
"And if you are thinking of risking dividing the Conservative vote and damaging so much the better chance the UK has for Brexit, then, for the sake of God – give up."
He said his party would present at least 600 candidates in the general election, unless the Prime Minister removes the allowance for the transition period to Brexit that will last until 2022.
Mr Farage has pledged to compete for 650 seats unless Mr Johnson renounces his contract with Brexit, but has since been asked to focus on a smaller number of call-ups. Referring to the Conservatives' refusal to reach an agreement with his party, Farage said: "It's not too late for Boris.
"He did not run his manifesto, a general election is a chance to press the reset button.
"I'd love to see him move from where he is."
When asked if Brexit Party candidates would step down, Ann Widdecombe said she was at a conference Monday where 450 candidates were registered and "nothing to suggest that they were retiring" .
