Vanessa Feltz is expected to take over as presenter of BBC Radio Two’s early morning radio show.
The outspoken Jewish broadcaster, who currently presents BBC Radio London’s morning phone-in programme, has been described as the frontrunner for the position.
The slot, which runs between 5am and 6.30, is followed by Chris Evans’ breakfast show.
Radio 2 is looking for a replacement for Sarah Kennedy, who left the BBC in September amid allegations she had a drink problem.
Her appointment has yet to be confirmed. A spokesman for the station said there would be an announcement “in the near future."
Ms Feltz, 48, has appeared on Celebrity Big Brother in 2001 and Ultimate Big Brother earlier this year. She was named Speech Radio Personality of the Year at the Sony Radio Academy Awards in 2009.
