Tony and Cherie Blair's former lifestyle guru Carole Caplin has been given the go-ahead to sue the Daily Mail for libel over her alleged portrayal as "some sort of sexpot or randy masseuse".

Caplin's advocate David Price QC complained that a September 2010 article in the newspaper also gave the impression she was a "Svengali or Rasputin-type figure" in the Blairs' marriage, reports the Daily Express.

Justice Sharpe backed the 49-year-old's claim that the article could mean that massages she gave to the former British Prime Minister involved sexual activity, which she denies.

It is also claimed and supported by the judge that the Daily Mail article headed 'Will Carole Caplin lift the lid on Blairs' marriage?' could bear the defamatory meanings complained of.

Publishing group Associated Newspapers had tried to halt the libel action by denying the meanings and asking the judge to rule that the article was not defamatory.

But the Justice found that the article, which said Caplin may consider accepting 1million pound to tell all about the Blairs' sex secrets after her gym business failed was capable of being so.
