Russell T. Davies has revealed that Bernard Cribbins will play the Doctor's companion in a two-part Christmas special.

The Doctor Who producer told BBC Breakfast that the actor would be back to reprise his role as Donna Noble's grandfather.

Discussing the four Doctor Who specials this year, Davies revealed: "It's a long and huge farewell to David Tennant."

"There's probably [a special] in November, then there's a huge two-part Christmas special," he added. "It's going to be massive, I promise you."
