Coronation Street Executive Producer Kieran Roberts is leaving after 16 years with the show and nearly 34 years with ITV.
Roberts said he had been thinking about leaving for more than a year, but had put the decision on hold when Coronation Street announced the production of a sixth weekly episode last summer.
With the new double Wednesday episodes successfully launched last week, Roberts has decided to step down at the end of the year.
During his time with the broadcaster, Roberts was Creative Director for drama from the northern-based production team. He has overseen production of Blue Murder, Mobile, Cold Blood, The Trials of Jimmy Rose, Midwinter of the Spirit and Tina and Bobby.
He is also a former producer of Emmerdale and won a BAFTA with the Yorkshire based soap in 2001.
