Andrew Castle has become the latest presenter to leave 'GMTV'.
The announcement of his departure follows Penny Smith's final appearance on the show last week and the news that another presenter, Ben Shephard, is also leaving shortly.
As part of a revamp of 'GMTV', Adrian Chiles is to become a presenter on the show.
The Press Association says Castle's last 'GMTV' will be in September.
In a statement, the former tennis professional said: "I have had a fantastic 10 years fronting one of the UK's most watched television programmes, but with all the changes taking place at 'GMTV' I felt it was time for a new chapter in my life as well.
"I enjoyed both meeting and working with some very talented people at the programme and I wish all those at 'GMTV' every success in the future."
Castle, who commentates on Wimbledon for the BBC, will be seen later this year in ITV's entertainment show '71 Degrees North'.
