The politician said recent polls signalled his party was in the running to add multiple MPs to the House of Commons after its only MP Douglas Carswell quit the party last month.
He told talkRADIO: “They only need something like a 4 per cent swing from Labour to Ukip to take the Hartlepool seat and the Conservatives are a long way behind.
“So seeing how unpopular Jeremy Corbyn has been with the Labour party and frankly if you’re a working class voter why on earth would you be considering voting for a Labour party under Jeremy Corbyn is beyond me.

Frankly, if you’re a working class voter why on earth would you be considering voting for a Labour party under Jeremy Corbyn
“So I think there are seats where Ukip does stand a real chance of gains and you know we’re supposed to have come through this horrific period for Ukip – what has been told has been absolutely awful and yet one of the polls at the weekend has us up on our general election vote share and had us at 14 per cent.”
The North East England MEP insisted he welcomed the election but bashed Theresa May for creating a “feeling of mistrust of politicians”.
He said: “Of course I do, I welcome anything that gives people more democracy – I want this election, of course I do.
“I just have this feeling it’s a little bit cynical by Theresa May and that it just does create this feeling of mistrust of politicians.

Jonathan Arnott welcomed the election but called Theresa May "cynical"
“I just don’t think that’s what our Prime Minister should be doing.”
The vote is set to take place on June 8 with MPs due to vote tomorrow in the House of Commons on whether to back her call.
Announcing the election, Mrs May said: “As we look to the future the Government has the right plan for negotiating our new relationship with Europe. We want a deep and special partnership between a strong and successful EU and a UK that is free to chart its own way in the world.
“That means we will regain control of our own money, our own laws and our own borders. And we will be free to strike trade deals with old friends and new partners all around the world.
“This is the right approach and it is in the national interest.
“But the other political parties oppose it. At this moment of enormous national significance there should be unity here in Westminster but instead there is division. The country is coming together but Westminster is not.”
