Nick Thorogood, editor of daytime at ITV, is to leave the broadcaster later this month.

The departure is part of a huge overhaul of management at Network Centre, which has also seen the resignation of Claudia Rosencrantz after ten years as entertainment commissioner and the appointment of Alison Sharman as the new director of factual and daytime.

Thorogood joined ITV from UKTV in November 2004 and oversaw the multimillion-pound relaunch of daytime as ITV Day. The strand has been plagued by a number of flops, including The People's Court and Nigella, but has also featured some hits, such as The Jeremy Kyle Show.

"Nick has achieved a phenomenal amount in the time he has been at ITV," said Nigel Pickard, ITV's director of programmes. "The Jeremy Kyle Show, launched as part of the ITV Day rebrand, has established itself as a key part of the schedule and several other shows have broken through to breathe new life into ITV's daytime programming. We wish Nick every success for the future."
