With Jonathan Ross announcing his exit from the BBC today, three of the hottest gigs in TV and radio are up for grabs – so which presenters and DJs will be eagerly waiting that phone call from the BBC?

Paul O'Grady is an old hand at the format, while ITV stalwart Harry Hill is thought to have rejected overtures from the BBC on many occasions. The lure of his own chatshow would surely prove too tempting to resist, however. Film 2010 Critic Mark Kermode has already emerged as a contender to front Film 2010. He is already on the BBC's Culture Show. James King, who may also be in the frame, is one of the presenters on film show ITV2 at the Movies and has fronted his own Radio 1 show, James King's Movie News. Another potential candidate is Jason Solomons, the Observer critic, who presents the Guardian's film podcast and has also presented numerous radio shows. Radio 2 Saturday morning Liza Tarbuck has filled in on Ross's Radio 2 show during absences. Industry insiders say that comedian and Radio 2 DJ Mark Lamarr could take over Ross's Saturday morning show in the short term. Comedians Alan Carr and Paul O'Grady are tipped as long-term replacements. Lauren Laverne is a rising star on BBC 6Music, but may not possess enough star quality. One may who has that in spades is Russell Brand. What odds on Brand making a dramatic return to radio by taking on his mate's show?
