Nigel Farage could become a "national hero" by urging voters to back the Conservatives, according to former Brexit Party MEP John Longworth.
Mr Longworth, who was sacked from the Brexit Party on Wednesday, said the "right thing" to do was give Boris Johnson's party a "free run" at the general election.
"I know when to take the cake out of the oven. There's no point having a burnt cake that crumbles, and that's what the Brexit Party are heading towards," he told talkRADIO's Julia Hartley-Brewer.
"They're going to destroy the possibility of this government - the only people who can deliver Brexit - taking votes away in key marginals."
Mr Longworth, right, had the whip removed this week
Brexit Party MEP's Annunziata Rees-Mogg, Lance Forman and Lucy Harris all resigned the whip of Nigel Farage’s party earlier this week to support the Prime Minister’s mission to “get Brexit done”.
Mr Longworth, who was accused of "repeatedly undermining" Mr Farage, said it was time for his former party's leader to follow suit.
"It is still possible that Nigel Farage could join us. I'd encourage him to come across. Actually it's a great victory for him. We've done it, we've got Brexit and he could be a national hero," he said.
"What we're doing is asking the voters to vote Conservative if they want to leave the EU."
He continued: "That's why I had the whip removed this week, because I wouldn't confirm to my party that I was going to vote against Boris Johnson's Withdrawal Agreement in the European Parliament."
Ms Rees-Mogg told talkRADIO that although she was "no fan" of Mr Johnson, she would support him in order to see Brexit delivered.
"He’s not my cup of tea but if he can deliver Brexit that’s who we’ve got to support," she added.
