Ukip is facing fresh controversy after a senior party official said that the party is proud to stand up for Britain's “hundreds of thousands of bigots,” The Sunday Times (£) reported.
The comments were made by the party's general secretary Matthew Richardson, who also described the NHS as the "biggest waste of money in the UK" in a video released last night.
A source told the paper that Mr Richardson said at a meeting last month: "I've said before, people talk about Ukip being bigots. There are hundreds of thousands of bigots in the United Kingdom and they deserve representation."
Mr Richardson insisted the comments were "clearly light-hearted harmless banter in the pub" and did "not reflect any seriously held belief".
The paper said that Mr Richardson was appointed last year "to put an end to the party’s series of public relations gaffes and to prevent 'bad stuff' about Ukip from making it into the media."
In a further blow to the party, Amjad Bashir, an MEP for Yorkshire and the Humber, defected to the Tories last night, denouncing Ukip as "pretty amateur" with a "ridiculous" lack of policies.
Ukip's general secretary Matthew Richardson has said the NHS costs too much money to run and is partly to blame for Britain's national debt, in a video released by the Labour party.
Mr Richardson is also reported to have gone on to say that Britain has "thousands of bigots" and Ukip is proud to stand up for them, according to The Sunday Times (£).
