SUPERSTAR couple David and Victoria Beckham were today due to start a High Court bid to ban a book based on revelations by Bolton minder Mark Niblett.

Mr Niblett, aged 35, was bodyguard to Spice Girls singer Posh and Manchester United Footballer Becks at their Cheshire mansion.

But the Beckhams say Mr Niblett, believed to be from the Horwich area, broke a confidentiality clause in his contract by speaking out.

The book, written by Princess Diana's biographer Andrew Morton, is full of personal details about the world-famous couple. They won a temporary injunction in July and now want a full injunction against the "kiss-and-tell" book appearing in shops.

It is reported the couple is set to sue Mr Niblett for breach of confidence.
