This edition's contestants are all former Big Brother winners. Stepping up to the plate are series 2 winner - quick-witted, cheeky Irish chappy Brian Dowling; Big Brother 5 champion - passionate, Portuguese Nadia Almada; 2007 winner - Essex wide-boy Brian Belo; and 2009's gorgeous victor - glamour model Sophie Reade. Brian Dowling regrets presenting a rather easy menu; Nadia is convinced that she's going to win with her authentic Portuguese menu; when Brian Belo plays host, there are farcical scenes as the novice chef attempts to prep his ambitious menu; and, on the final night, 'stranger to vegetables' Sophie hosts, with a minimal menu and an even more minimal outfit. Which of the Big Brother winners will be crowned the Champion of Champions and win the £1000 charity prize?
