Labour has called for the sacking of Ukip's general secretary after a video was released yesterday showed him comparing the NHS to Hitler's Nazi bunker.
The comments from Matthew Richardson - made when he was a member of the Conservative party - were condemned by shadow minister without portfolio Jon Trickett, who said they reflect "Ukip's real agenda on the NHS".
"Nigel Farage cannot simultaneously defend these comments and claim that his party stands for the NHS free at the point of use," he said.
Trickett added: "They claim to defend the service we cherish, but they want to dismantle its foundations."
Farage has denied that he wishes to privatise the NHS, and the party today announced plans to inject £3 billion into frontline services using money saved by leaving the European Union.
Nigel Farage has accused his political opponents and the press of running "the most negative general election campaign ever" following a series of claims about the party's candidates and members.

Richardson was also accused of saying that bigots "deserve representation", a comment the Ukip leader claims was simply an old joke.
"The fact that we get hear'say from gossip and jokes in pubs on the front page of newspapers says to me we are going into the most negative General Election ever," he said.
