BBC Three Counties Radio – which covers Bedfordshire, Buckinghamshire and Hertfordshire – is to have it's biggest line-up change in three years.
Lorna Milton moves from afternoons to co-host on breakfast, with Ronnie Barbour replacing her. There's also a new hour-long midday news programme.
The changes will take effect from Monday 24 January
Breakfast with Simon Lederman and Lorna Milton will be followed by Jonathan Vernon-Smith who moves two hours earlier to 9am with a phone-in and consumer hour.
Roberto Perrone stays on drivetime, which will introduce a nightly round-table debate from 6pm. After the midday news programme, Ronnie Barbour will present 'The Other One Show'.
The opt-out breakfast show for Milton Keynes will continue, with Helen Legh due to return to the show in March following her maternity leave.
Weekends on the station are changing too, with former Heart presenter Gaz Wesley presenting a newly extended Saturday morning show from 9am, followed by 'Nick Coffer's Weekend Kitchen' from midday.
Brett Spencer, Managing Editor, BBC Three Counties Radio, said: "It's the biggest change the station has had for more than three years, and I'm confident that the new line up combined with improved local news and original journalism will encourage existing listeners to listen for longer and also attract a new audience as well."
