Ladbrokes spokesman Warren Lush said: "Public demand has forced us to produce a long list of possible Doctors despite the fact that David Tennant is so hotly tipped for the role.
"Before Eccleston took the role the money was for Alan Davies and Eddie Izzard and they have to be seen as possible contenders again."

Other contenders include Alan Davis, Bill Nighy and Eddie Izzard. Ladbrokes have even included a real doctor, the comic Harry Hill, but at odds of 1000/1. Alan Cumming, another Scot, is in the running. But are we at the Diary the only ones who think it is obvious that it should be none other than Billy Connolly? That would be just ticketyboo." - The Scotsman - April 1, 2005
