The editor of ITV1’s morning show Daybreak is to leave the show he launched less than a year ago.

Ian Rumsey said he was looking for a “new challenge” after being at the helm since the programme went on air last September, replacing GMTV.

The show, fronted by Adrian Chiles and Christine Bleakley, was criticised for struggling to match the GMTV audience in its early stages, but has since found its feet with around 800,000 tuning in. It is drawing about half the figures of its BBC1 rival Breakfast.

Mr Rumsey will continue with the show until the end of the year.

He said: “This was a tough decision. I’m very happy to stay until the end of 2011 but I really do feel like a new and different challenge in the new year.

“Daybreak has a remarkable and resilient team of people working on it. I’ve been proud to have been their editor and wish them great success in the years ahead.”

Staff on the show are being “integrated” into a different production team, ITV Studios, which produces much of the station’s morning output as well as afternoon show Loose Women.

ITV’s director of television Peter Fincham said Mr Rumsey had “laid the foundations on which we can build and develop Daybreak”.

Mr Rumsey, 40, joined Daybreak after editing ITV’s General Election programme. He had previously edited each of the major network news programmes for ITV.
