Fake Sheikh buys his way into Buckingham Palace

The Fake Sheikh strikes again. Safety for the Queen and Royal Family is being urgently reviewed after a Buckingham Palace security breach engineered by Britain's most notorious undercover reporter.

Mazher Mahmood, the News of the World investigations editor best known for passing himself off as a bogus Arab princeling, claims to have been given an extensive tour of the car fleet inside the Palace by bribing a chauffeur.

Mr Mahmood claimed that he and a colleague, posing as curious Middle Eastern businessmen, gained extensive access to the royal limousines and the Queen's personal Rolls-Royce and Daimler, after being admitted unchallenged into the Royal Mews.

They were allowed to photograph and video the vehicles, including their number plates, were told their official code names and given details of security weaknesses, and even permitted to sit inside one of them unsupervised – with enough time to have planted a bomb, Mr Mahmood claimed.
