Jeremy Clarkson hosts the big-prize quiz in which another line-up of contestants answer questions that could change their lives - with the lifelines Ask the Audience, Phone a Friend, 50-50 and Ask the Host available to them if they get stuck.

Jeremy Clarkson hosts a special festive edition of the quiz. Sports presenter Clare Balding, actor Stephen Mangan and Coronation Street's Catherine Tyldesley each sit in the hot-seat, hoping to win £1million for their chosen charities, and as usual they will have four lifelines to help them along the way - Ask the Audience, 50:50, Phone a Friend and Ask the Host.
