Could Tom Cruise be buying into London's most expensive block of flats? Sources say the actor has been looking at One Hyde Park, the Candy & Candy scheme in Knightsbridge where flats are selling for £25m and up. The couple and their daughter, Suri, have been staying at the Mandarin Oriental hotel next door. When One Hyde Park is finished, in 2010, the hotel will be running its facilities - so perhaps the Hollywood star is testing them.
