BREXIT Party boss Nigel Farage has given Boris Johnson 24 hours to make an electoral pact with him.
Mr Farage will reveal on Friday how many candidates he plans to field as Tory chiefs warn he could let Labour chief Jeremy Corbyn into No10 by splitting the pro-Brexit vote.
He had threatened to stand in all 650 seats but it emerged on Wednesday night he may slash it to just a few dozen.
A source close to Mr Farage said: A Leave alliance would win a big majority.
In a cryptic message, the Brexit Party told all candidates on Wednesday: Important. Please all go DARK on social media.
DO NOT respond to any questions about where we (are) standing, what the strategy or plan is from now on. Things will be made clear…very soon.
It also emerged that two Brexit Party candidates are former Communists. Husband and wife John and Yasmin Fitzpatrick will stand in North Thanet and East Surrey.
The Sun can reveal that both stood for election for the Red Front in 1987, a communist faction which pushed a series of hardline positions including the reunification of Ireland.
A Tory MP on Wednesday night claimed the Fitzpatricks selection cast heavy doubt on how well Mr Farages new party has screened extremists from representing them.
Tory MP Mark Francois mocked the Brexit Party for selecting candidates who were too Left-wing even for Jeremy Corbyn.
He said Bill Cashs Brexit Party opponent had stood down out of respect to the Tory MPs years of trying to leave the EU and urged others to ask themselves if they should do the same.
A Brexit Party spokesman said they welcomed candidates who believe in democracy, no matter their political background.
He added: This is not an issue of left and right, its an issue of right and wrong.
