Allister Heath is off the the Telegraph so that leaves a major vacancy as editor of City AM. As ever MediaGuido gives you the runners and riders for the job:

• Iain Dey – Currently deputy business editor of the Sunday Times, Dey is one of the names being pushed hardest. A former Business Journalist of the Year, he is seen as sound enough having been instrumental in his paper’s campaign to overhaul business rates.

• James Ashton – Head of Business across the Evening Standard, Indy, Sindy and i, Ashton is also tipped to be a name to look out for. Might he leave a Lebedev London title for the number one job at a rival in the City?

• David Hellier – Perhaps City AM will go for an internal hire and promote their deputy editor of nearly 8 years. Described as “a safe pair of hands”, Hellier knows everyone in the City and is in with the investment banking crowd, giving him knowledge of deals.

• Marc Sidwell – Or they could give the job to their current Managing Editor. Sidwell is seen as a likeable and principled free-marketeer, he has strong connections to the world of think tanks.

MediaGuido’s inbox is always open for insiders with any more tips for the post. A gruelling job awaits for whoever wins the race…
