A third series of Russell T Davies' Doctor Who is due to air in spring 2007, following a Christmas special this year.

It will see actress Freema Agyeman, 27, taking over from Billie Piper as the Doctor's assistant. The BBC recently announced a Doctor Who spin-off starring Elisabeth Sladen, who played one of the doctor's companions, Sarah Jane, in the 1970s.

That series will kick off with a one-hour special early next year.
