This year’s BBC Children in Need is to feature an exclusive preview of the forthcoming Doctor Who Christmas Special.

The clip, from The End Of Time: Part One, is never-seen-before footage and will keep fans all over the globe wondering what’s in store for the Doctor as David Tennant departs and Matt Smith becomes the 11th Doctor.

David Tennant said: “Doctor Who has always been a big supporter of Children in Need. We’re really pleased that this year our very special Christmas story is being exclusively previewed on the show. Doctor Who fans are always very generous – I hope you will be too. Please give what you can.”

The two-minute exclusive will be broadcast as part of the BBC Children in Need show tonight (Friday 20 November), BBC One at 7.00pm.
