Just seen on the Mail website, that 2 of the people it could be are
Dame Helen Mirren and comedienne Miranda Hart , I hope not, Mirren is OK but not for the Doctor, but I cant stand Hart, I think she is dreadful.
The Thick of It star Peter Capaldi is another one, he could do a decent job.
This IS in The Guardian online
Bookmakers have installed Capaldi, best known as the profanity-spewing spin doctor Malcolm Tucker in The Thick of It, as the favourite. Twitter users suggested a few Tucker-esque one-liners for Capaldi for the more family-friendly role, using the hashtag #tuckerwholines. "Oi, Dalek. Stuff your lollipop up your shiny metal arse, you mincing tin twat," .
Cutting It star Ben Daniels is also in contention, as is Skyfall actor Rory Kinnear. David Harewood, Olivia Colman, and Billie Piper also get a mention.
