After four weeks of intense competition, 12 most talented chefs from the initial 48 face knockout week. Tonight is the first time they all come together in the MasterChef kitchen, where their fate rests in an almighty cook-off.

The second group of five chefs face two intense challenges. The chefs must cook together for the first time as a team to create an exceptional three-course fine-dining menu at one of London's most prestigious addresses, The Institution of Civil Engineering, to celebrate the organisation's bicentenary. Will their creative vision and talent shine through? Or will team playing prove to be their weakness?
