Former Radio 1 DJ Simon Bates is being replaced as the presenter of the breakfast show on Global Radio's Smooth Radio in a revamp of the station that sees new shows for Andrew Castle, Kate Garraway and Myleene Klass.
Castle, the former tennis player who commentates for the BBC during Wimbledon and was a regular presenter of GMTV, takes over the breakfast slot, with another breakfast TV presenter, Garraway, presenting the mid-morning show on Smooth.
Garraway replaces another former Radio 1 DJ on the station, Lynn Parsons.
Klass, the former Hear'Say singer who is a veteran of Smooth's sister station, Classic FM, will host a Saturday show up against Radio 2's Graham Norton, between 10pm and 2pm.
The station, bought by Ashley Tabor's Global from Guardian Media Group two years ago, part of the GMG Radio stable of stations, will relaunch on 3 March with a new strapline,Your Relaxing Music Mix.
Bates joined Smooth in 2010 from Classic FM, where he spent the previous 13 years.
A spokesman for Bates said the presenter's three-year contract with the broadcaster had come to an end and his departure was "amicable".
Castle will present the breakfast show on the London Smooth Radio, with a Sunday evening interview show, Andrew Castle Meets, broadcast across the network.
In an almost complete overhaul of the Smooth lineup, former Magic 105.4 presenter Paul Phear will present weekday afternoons. Anthony Davis remains on the drivetime show with Tina Hobley staying in the Sunday morning slot.
Davis will present a new Sunday evening show, Great American Songbook, and Chris Skinner a show called Great British Songbook on Saturday nights.
Tabor said it was an "all-star cast".
"Andrew Castle, Kate Garraway, Tina Hobley and Myleene Klass joining Smooth tell you just how seriously Global takes the launch of Smooth, and the focus and investment we're putting behind this brand," said Tabor.
"It's a further demonstration of our core strategy of 'national brands delivered locally', and it's very important to us. As Smooth becomes one of the country's biggest commercial radio brands, we're investing to make it bigger and better for our listeners and advertisers."
