The fallout from "jaw-dropping" racist remarks made by a former Ukip councillor in Thanet are continuing to dog the party this week as it gears up for a key conference in Margate.

The party had hoped its conference at the Winter Gardens, beginning on Friday, would provide it with a springboard for its election campaign - with leader Nigel Farage hoping it would provide a boost to his own efforts to become MP for Thanet South.

He is making a keynote speech on Friday in which he is expected to try to draw a line under the controversy.

However, the party is being dogged by a backlash over the comments made by Cllr Rozanne Duncan, who was expelled from the party in December after officials said she had brought it into disrepute.

The row is also expected to swell the number of anti-Ukip protestors planning a march around the town on Saturday.

It has emerged Thanet council has already received complaints about her views and calls for an investigation into whether she has breached the authority's code of conduct.

The comments were finally broadcast last night on the BBC 2 fly-on-the-wall documentary, Meet The Ukippers.

The programme showed Mrs Duncan saying she had a problem with people with "negroid features."

It features the now independent councillor saying to colleagues she "doesn't like Negroes because of how they look".

She adds: "I don’t know why. I don’t know whether there is something in my psyche, whether it is karma from a previous life, whether something happened to me as a very young person and I have drawn a veil over it because that sometimes happens, doesn’t it? But I really do have a problem with people with Negro features, I really do."

She goes on to say: "A friend of mine said, ‘What would you do if I invited you to dinner and put you next to one?’ I said, 'I wouldn’t be there, simple as that'."

The documentary also showed one Ukip councillor's frustration at the attention given to his brief membership of the National Front.

County councillor Martyn Heale is filmed saying: "I was a member of the Conservative party for 22 years, a member of National Front for one year - why don’t they just get over it?"

Thanet North MP Sir Roger Gale has appealed to Ukip members to consider whether they should continue to be in a party that he says represents a lurch to the hard right.

In his column for KentOnline's sister paper the Thanet Extra this week, he writes: "What I do know, from canvassing in South Thanet in support of the Conservative Craig McKinlay, is that I have been joined by Tories who, having flirted with Ukip, have listened to the backchat inside that tent, have not liked what they have heard and have returned determined to exorcise that brand of nationalism from our political system."
