More voters think Ukip is a racist party, a new opinion poll has revealed. According to a ComRes/ITV poll, 44% believe the anti-EU party has a racist agenda. Meanwhile, the number of people who think Ukip is not a racist party sits at 36%.

The results of the poll of 2,059 people come soon after Nigel Farage's party was rocked by BBC2 documentary Meet The Ukippers.

But worryingly for the Ukip, most of the polling was done before the show was aired on the BBC. Viewers saw one Ukip councillor confess on the BBC show that she disliked "negro" faces.

Rozanne Duncan, who sits on Thanet District Council, told film makers for the documentary: "The only people I do have a problem with are negroes. And I don't know why."

Rozanne Duncan's remarks got her expelled from Ukip, a party that bans right-wing extremists from membership, in order to counterclaim it is racist at heart.

Duncan now represents Cliftonville East - in the Thanet South seat where Ukip leader Nigel Farage is running for Parliament - as an independent councillor.

Despite these setbacks, Ukip remains the most trusted party to tackle immigration, according to the poll.

David Cameron has been embarrassed by the latest immigration figures showing around 300,000 entered Britain last year. It makes a mockery of the Tory pledge to cut numbers to the tens of thousands.

According to the poll, a total of 36% of voters trust Ukip on immigration, with the Tories lagging far behind on 19% - only five points ahead of Labour on 14%.
