Labour accused David Cameron of a swing to the right yesterday after it emerged the Conservative leader had appointed as his special adviser a man who previously called for "a period of creative destruction" in the public services.
Danny Kruger was forced to withdraw his candidacy for Tony Blair's Sedgefield seat in last year's election due to the embarrassment caused to Mr Cameron's predecessor Michael Howard by his comment.
A Daily Telegraph leader writer and son of celebrity chef Prue Leith, he is expected to write high-profile speeches for Mr Cameron and liaise with head of policy development Oliver Letwin's office.
He has previously worked as a speech-writer for Iain Duncan Smith during his time as Tory leader and as director of studies of the right-of centre economic think-tank the Centre for Policy Studies.
Labour chairman Hazel Blears said: "Danny Kruger had to quit as a Conservative candidate during the last General Election campaign when his extreme views were revealed. Kruger represents the extreme wing of the Tory party who want 'a period of creative destruction in the public services' and he believes the 'NHS must, in effect, be abolished'.
"That David Cameron appears to believe Danny Kruger is the person to advise him reveals the true face of his party now.
"This appointment shows the Tories haven't changed. Cameron says whatever he thinks people want to hear but the reality is that the substance of his Tory party is as right-wing as it has ever been."
A spokesman for the Conservative Party confirmed Mr Kruger's appointment, adding: "Hazel Blears' comments are totally unwarranted and completely without foundation."
