The owners of a historic London casino have sued a high-stakes international gambler said to have once lost £2.4m in a night after complaining that they are owed £470,000.

PETER HARRISON, the backer who has sunk a reported £22m into Britain's America's Cup Challenge, was last night wearing his widest smile of the week after his Farr 52 Chernikeeff 2 won the showcase IRM High Performance Class's 24.2 mile coastal race.
