The six best celebrity cooks remain, but at the end of the day two will be sent home for good. They must cook a two-course meal for 30 schoolchildren, and then make the perfect roast dinner to show judges John Torode and Gregg Wallace that they deserve to stay in the competition.

The four semi-finalists are sent to some of London's best restaurants to fine tune their individual cooking styles - before coming back to the studio to show judges John Torode and Gregg Wallace exactly what they've learnt. And they must then take on the challenge of being the sole caterers at an exclusive society dinner.

The four semi-finalists must cook their best two-course meal to impress three of the country's most respected food critics. And the pressure is really on as at the end of the show, judges John Torode and Gregg Wallace decide which one of the celebrities must leave the competition.

The three finalists are faced with their toughest challenges yet - from feeding 90 crew members of the hit drama Ashes to Ashes to producing fine dining at a charity fundraising dinner at the top of the BT Tower.

The three finalists are flown to North Africa and have to master traditional cooking techniques as well as exquisite fine dining. Their final challenge is to cook a three course meal at Theo Randall's renowned Italian restaurant for five of the Godfathers of French cooking - including Michel Roux and Michel Roux Jr.

It's the grand final of Celebrity MasterChef. The three finalists have to cook their best three-course meal for one final judgment from John Torode and Gregg Wallace. Only one of them can be crowned Celebrity MasterChef Champion.
