Jon Culshaw's big break came when convincing the then Prime Minister, Tony Blair, in a prank phone call that HE was the then Conservative leader William Hague - an infamous moment in his life for which he was called an imposter. Since then, he’s built up a repertoire of 350 celebrity voices, starred in 23 series of Dead Ringers and joins us live from the Edinburgh Festival where he’s starring in his new show, Imposter Syndrome.

Tommy Jessop is an actor, a campaigner and has just had his first book published, 'A Life Worth Living’. In 2007, he became the first actor with Down Syndrome to star in a primetime BBC Drama in the film ‘Coming Down the Mountain’ and has gone onto tour theatres as Hamlet and played Terry Boyle in 'Line of Duty’.

This year’s Great British Sewing Bee champion Asmaa Al-allak spent her formative years growing up in Iraq. Her grandmother was a seamstress who passed her skills on to Asmaa’s mother, who in turn taught her and after winning the series, Asmaa said it’s fair to say ‘it’s in the blood’. After leaving Iraq at the age of 14, having lived through the Iran-Iraq war, Asmaa and her family moved to Durham where her father was working as a scientist. She went on to study medicine and is now a consultant breast surgeon at a cancer centre in Cardiff.
