Plot
Derek is off to his office party. Sally invites Jenny for Christmas but she refuses and when Rita phones her she puts the phone down on her. Mike asks Alma to spend Christmas with him but she refuses. A very drunken Derek, dressed as Santa Claus, gets locked in the Novelty Warehouse. Vera and Jack forgive Curly and Jack invites him for a drink at the Legion. On the way back Jack is convinced that he has seen Santa Claus on the roof - in reality, Derek trying to get out. A sing-song in the Rovers is led by Percy but Mavis is purse-lipped as Derek is still missing. Ken finally arrives home and reveals to Deirdre he is having an affair with Wendy Crozier.
