Ben Shephard is back with a brand new series of Tipping Point: Lucky Stars, the quiz show in which three celebrities take on an extraordinary machine in the hope of winning £20,000 for charity.

This week QI and Jonathan Creek star Alan Davies, comedy actress Sally Phillips and TV doctor Ranj Singh will each need quick wits and nerves of steel if they're to capture the prize.

Ben Shephard invites former footballer David Ginola, broadcaster Janet-Street Porter and reality TV star Chris Hughes to take part in this celebrity edition of the quiz show, in which contestants answer questions to win turns on an arcade-style machine, winning cash with each successful drop.
