Roger Helmer, the Ukip MEP for the East Midlands, is to fight the parlimentary by-election in Newark next month.
He has been out in the constituency today speaking to voters about the seat he will contest instead of party leader Nigel Farage who said his candidacy would be a distraction.
The seat was vacated by former Tory MP Patrick Mercer who resigned after a cash for questions scandal.
The by-election will be held on June 5.
The Conservatives have selected Robert Jenrick to try to retain the seat after Mercer's resignation while Labour's candidate is Michael Payne.
The Liberal Democrats are expected to announce their choice in the coming days while the Buss Pass Elvis party are also likely to announce their runner.
UKIP's Yorkshire and North Lincolnshire candidate for the European Elections says the party should be included in televised debates in the lead up the the General Election.
Jane Collins says the party deserve the opportunity to share a stage with the major parties:
A Lincolnshire UKIP councillor's denied making offensive and politically incorrect comments about immigrants. Victoria Ayling says a video of her saying she wants to "send the lot back" actually refers to people who are living in the country illegally. Michael Billington reports.
A Lincolnshire UKIP councillor's denied making offensive and politically incorrect comments about immigrants. Cllr Victoria Ayling appeared in a video discussing immigration in 2008 where she's heard to say "send the lot back". She told ITV News Calendar the comments were taken out of context.
Shadow immigration minister David Hanson called for an apology after comments made by Ukip councillor Victoria Ayling.
"This type of offensive language should have no place in modern Britain," he said.
"British people do not deserve to be 'sent back home' because this is their home.
"It has taken us years to defeat the ideology and language of the NF [National Front] and the views of the BNP [British National Party] and they should not be resurrected by someone calling themselves a serious politician.
"She needs to apologise and repudiate the use of this type of language and thinking."
Ukip says it will stand by Victoria Ayling and has dismissed allegations that she holds extreme views.
"These comments were made 5 years ago when Ms Ayling was a Conservative candidate. Off the cuff remarks have been deliberately misconstrued. We believe, and she assures us, that these comments refer to the status of illegal entrants to the UK. We cannot comment on material made while she was a Conservative candidate but we believe her to be a good councillor and upstanding citizen and will support her through this."
Other remarks made by Ukip councillor Victoria Ayling in the Daily Mail video include:
...send them back.
[Rob Ayling] It's a bit National Front isn't it?
[Victoria Ayling] It's right though. But anyway...
Multiculturalism does not work - Britishness does.
[Away from camera] Multiculturalism is dead, I'm allowed to say that but maybe 'Britishness' is waving the National Front flag a bit.
I just want to send the lot back, but I can't say that.
[Rob Ayling] We'll nip that out in case...
[Victoria Ayling] Bribery, blackmail! We need the blackmail music, don't we!
Victoria Ayling told the BBC that her "send the lot back" comments were made in reference to illegal immigrants and that the Mail story was based only on "snippets" of the political video she made with her husband in 2008.
Ukip leader Nigel Farage told the Daily Mail that Victoria Ayling’s comments were "slightly odd", but added:
I have met her two or three times and I have discussed policy at length before accepting her into the party.
I had no reason to believe she held views that were extreme or inconsistent with ours.
While this comment looks odd and unpleasant there may be a context here that is slightly different to the way it appears.
Ukip politician Victoria Ayling has hit her party with a new racism row after footage was published in which she said all immigrants to Britain should be sent home.
In video filmed by her then-husband Rob Ayling in 2008, the councillor makes off-the-cuff remarks including: "I just want to send the lot back but I can’t say that."
The film, published by the Daily Mail, includes multiple takes of Ayling's attempts to explain her personal views on immigration - but also her comments to her husband behind the camera between takes.
The Ukip member defected from the Conservatives earlier this year.
