Philip Rhys - a UK actor starring in BBC's new adventure series Survivors with Freema "Martha Jones" Agyeman and Paterson Joseph - had a little slip-up during an interview on BBC News 24 tonight: “Yeah, we have a great cast. Max Beesley, Freema and Paterson Joseph .. y’know, the new D.. potentially the new Doctor.” And then the good Mr Rhys looked mortified and the interviewer quickly changed topic. Potentially? Let the speculation continue, although I suspect this might be confirmation enough for a lot of people.
Addendum: Behind The Sofa picks up on the potential slip-up. They've posted a link to a youtube clip of the interview.
