The BBC has begun searching for a new boss to take the helm of Casualty and Holby City.

Current executive producer Johnathan Young has been in charge of the popular dramas since March 2011, but his two-year fixed-term contract will soon come to an end.

According to Broadcast, the BBC is now advertising for a successor and it is currently unclear whether Young intends to reapply for the position.

Young took over from Belinda Campbell on the programmes after five years at Talkback Thames.

He was The Bill's executive producer for its final five years on the air and was also one of Holby's original producers in 1999.

Young's current post sees him oversee both of the BBC's prime-time medical dramas, working with Nikki Wilson and Justin Young, who are the series producers of Casualty and Holby respectively.
