Sara Cox is the favourite to become the new presenter of rebranded BBC Radio 2 Drive following the departure of Simon Mayo.
The DJ has presented the show since 2010, but Mayo will vacate the 5-7pm slot to focus on writing commitments.
Cox was heavily tipped to take over from Chris Evans as presenter of the Breakfast Show, but lost out to Zoe Ball.
She is now the 6/4 favourite to fill the drivetime slot, with Claudia Winkleman, Graham Norton and Richard Madeley touted as possible presenters of a potentially rebranded show.
These are the odds on other contenders, according to bookmaker Paddy Power:
Mark Goodier – 6/1
He has also worked on Class FM, Smooth Radio, and BBC Radio 1. He has experience in the drivetime slot, making him a potentially safe choice for producers.
Steve Wright – 8/1
Moving Wright from this slot to slightly later in the day would be a safe choice for producers, and the presenter is the third favourite.
Liza Tarbuck – 10/1
Claudia Winkleman – 12/1
Another Radio 2 talent, she could be reassigned to a more regular weekday slot.
Richard Madeley – 16/1
Nick Grimshaw – 16/1
The BBC could potentially change his station and maintain the presenter’s role as a drivetime host.
Graham Norton – 33/1
However, TV commitments might make it less likely that he will be able to take on regular weekday shows.
