The leader of the Brexit Party has said he would put “country before party” and join forces with the Conservatives to deliver Brexit.
Nigel Farage said a coalition between the parties would make them "unstoppable" in a general election, but that it was "up to Boris Johnson".
However, he insisted that the offer stood on the condition that the Prime Minister does not pursue a “reheated form” of Theresa May’s Withdrawal Agreement, which was rejected three times in Parliament.
"I have already said that to the 28 members of the European Research Group, who three times voted against that treaty, we will not stand against them," he told talkRADIO's Julia Hartley-Brewer.
"We will encourage people to work for them and support them, and that offer is open to other Conservative MPs as well."
He added: "I cannot do more than I'm doing to try and help people who want to get a proper Brexit."
So far, the Conservatives have repeatedly rejected offers to collaborate.
Asked about the likelihood of a general election, Mr Farage said he did not anticipate one to be held before the October 31 Brexit deadline.
The government is expected to face defeat in the Commons today as it puts a motion for an early general election to MPs for a second time.
Labour abstained from the last vote on the matter, with Jeremy Corbyn saying he would only back an election once he knew a no-deal Brexit was off the cards.
Mr Farage said: “If this Conservative government doesn’t take us out on October 31, support for the Conservatives will once again collapse.
“The Labour Party cynically knows that, so they’re prepared to put party advantage above delivering on the promise of their own manifesto in 2017, when they said they would respect the result of the referendum.”
However, Mr Farage did say he believed the country would hit the polls before the end of the year.
