Famous for: Grappling with horses and complex personal relationships in Rough Diamond
Most TV fans will recognise Conor Mullen as Aidan Doherty, the stable owner who's fallen on hard times in BBC drama Rough Diamond. While his on-screen persona has a reputation for being a commitment-shy ladies man, in real life Conor is happily married to actress Fiona Bell, whom he met on the set of Soldier Soldier in 1991. The Irish-born talent has been a firm fixture on British TV for the last 20 years, with appearances in The Bill, Murder Prevention and Heartbeat. In a less visual role, he also provides the voice of the speaking clock in his native Eire.
