Nigel Farage has announced he will "never ever" use the word manifesto, as the European elections approach.
When pressed on what the party's domestic policies would be, the Brexit Party leader said he would "not discuss" it until the EU elections were over.
"We're fighting a European election in 10 days' time. An EU election on European issues in the wake of the greatest ever vote in the history of our nation, and I am not going to discuss domestic policies between now and next Thursday," he told talkRADIO's Julia Hartley-Brewer.
"This is a deliberate tactic being used by everybody else because they want to get away from having a proper debate about the extent of which our Brexit vote - and the promises made to us at the general election - have been betrayed."
He added: "Thereafter, of course we'll talk about policies, but I will never, ever use that word manifesto. I think in most people's word association, manifesto equals lie."
According to an Opinium poll for the Observer, Farage's Brexit Party is set to secure more support at the European elections than the Conservative Party and Labour Party combined.
It suggests that more than a third of voters will back the Brexit Party on May 23, with a predicted 34 per cent of the vote. The Conservatives currently stand at 11 per cent, with Labour on 21 per cent.
"I was in semi-retirement, I was quite happy there, I didn't need to come back," Farage added.
"I only did it because the government and Parliament have made a total mess of it. And I believe if we leave the Labour and Conservative parties to deal with this, we will never get the Brexit we voted for."
Nigel Farage will be standing for the Brexit Party in the South East, alongside candidates from Change UK, the Conservatives, Green Party, Labour, Liberal Democrats, UKIP, UK EU Party, Socialist Party of Great Britain and three independents.
