PRIME Minister David Cameron has defended his government's record as the parties stepped up their campaigning ahead of the general election.

Mr Cameron said Tory plans for post-election spending cuts were "moderate".

He also responded to Labour's latest attack over the NHS, saying he would commit the funds needed to shore up the service in the future.

Labour has said the NHS would be left "unrecognisable" if the Conservatives win the election.

Speaking on the BBC's Andrew Marr Show days after unveiling the Conservatives' first campaign poster for the general election, Mr Cameron said he was "very happy" to be judged on his record since 2010.

Labour said the Conservatives' deficit attack was based on "false assumptions and out-of-date economic forecasts", while the Lib Dems said only they offered a "fair and balanced approach".

UKIP leader Nigel Farage said the prime minister had been "incredibly rude" about his party while trying to "sound a little bit like us".

In a "start of the race" note to activists, Labour's election strategy chief Douglas Alexander called for a campaign to "save" the health service.

The document claims waiting time rules have been breached and says there is a "staffing crisis" in the NHS.
