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.
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.
After Labour released a video of Ukip general secretary Matthew Richardson calling the NHS "a wasteful socialist programme", Farage told ITV News Political Correspondent Carl Dinnen that the major parties were trying to "damn" his party.
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.
India and the United States have broken an impasse standing in the way of civil nuclear trade, Indian media reports.
The breakthrough comes as Obama and Indian Prime Minister Narendra Modi met in New Delhi.
The reports said that the pair had ironed out differences on the liability of suppliers to India in the event of a nuclear accident and the United States had dropped its demand to be able to track the whereabouts of nuclear material supplied to India.
US President Obama was given an elaborate welcome at the country's presidential palace in New Delhi.
He walked in his socks to place a commemorative wreath honouring the father of India's independence movement, Mahatma Gandhi.
Tomorrow, Mr Obama was to be the guest of honour at India's Republic Day festivities, making him the first US president to attend the anniversary of the enactment of country's democratic constitution.

EU migrants living in Britain should not be allowed to vote in a referendum on Europe, Nigel Farage has said.
Speaking on The Andrew Marr Show, the Ukip leader said his party could go into coalition with the Conservatives, as long as they offered an immediate referendum on EU membership under specific terms.
Speaking on BBC's The Andrew Marr Show, he said: "At the moment, there are four million or so EU citizens living in Britain that I do not think should be allowed to vote in that referendum."
During the interview, Farage also said his party would spend an additional £3 billion on frontline NHS services - using part of the £10 billion Ukip says it save by withdrawing from the EU.
The party says it also force migrants and tourists to pay for health insurance as a condition of entry, which it claims will save £2 billion of "wasted" money on "health tourism".
The head of Greece's Syriza party, Alexis Tsipras, appeared confident this morning as his country went to the polls. Syriza remained head of conservative prime minister Antonis Samaras' New Democracy party in opinion polls leading up to vote, which is being held nearly two years ahead of time.
Tsipras has run on a campaign of renegotiating the country's 240 billion euro international bailout deal, and has pledged to reverse many of the unpopular reforms Greece agreed to in order to qualify for the package that has kept the country financially afloat. Speaking this morning as he was mobbed by reporters he said his message for Europe was simple: The "vicious cycle of austerity is over".
Nigel Farage says Ukip was becoming "increasingly alarmed" by MEP Amjad Bashir's behaviour in the months leading up to his defection to the Conservatives.
Speaking on BBC's The Andrew Marr Show, the Ukip leader said there was "quite strong documentary evidence" relating to what the party calls "unanswered questions" over employment practices at his business.
He also accused the MEP of "continuing associations with political extremists from Pakistan despite us saying please, please keep away", and said he was surprised that the Conservatives had accepted him
Bashir has denied any wrongdoing in relation to the allegations, and says Ukip's claims are a "desperate attempt" to smear him.
