Indeed we are going to highlight it every night this week; it's for a good cause and you'll miss it when it's gone. That being from tomorrow onwards. In this last instalment, TV presenter Claudia Winkleman (who better get that fringe out of her eyes and those sleeves off her mitts before she starts tackling any pies, you're not an EMO Blinkleman, sort it aaaaaht), comedian Ed Byrne (who also better tie up his Darlene locks), broadcaster Martha Kearney and Olympic gold medal-winning rower Helen Glover try to impress judges Mary Berry and Paul Hollywood. They attempt a signature bake of chocolate biscuits, make lemon meringue pie in the technical challenge and finish with a show-stopping cake to celebrate Comic Relief's 25th anniversary. Mel Giedroyc oversees proceedings and Lorraine Pascale presents another report from Ghana.
