Nigel Farage has confirmed he will not vote for the Conservative Party at the general election.
It is unclear who the Brexit Party leader will now back, after standing down his own party's candidate in the seat where he is likely to vote.
Mr Farage said he "wanted to" vote for Boris Johnson's party, but changed his mind after the Prime Minister talked about his "oven ready deal".
"I listened to him in a debate last Friday and he's now talking about an oven ready deal," he told talkRADIO's Julia Hartley-Brewer.
"That is a new EU treaty that binds us to regulated alignment... we will not be making our own laws so the answer is no I will not vote for them."
Mr Farage said this year's election was more about "who you're not going to vote for", and said the process was "overwhelmed with negativity".
His comments come after he announced the Brexit Party would change its name to the Reform Party after Britain's exit from the EU.
"We need genuine, fundamental political change and reform, so I am the new radical," he added.
"We want to get rid of the House of Lords, we want to get rid of the postal vote register which is open to fraud, abuse and intimidation, and have a more representative form of democracy."
Last week, three Brexit Party MEPs quit the party in order to back Boris Johnson’s Brexit deal and the Conservative Party.
And John 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.
He said Nigel Farage could become a "national hero" by urging voters to back the Conservatives.
