The Doctor will be joining in with the Children in Need party tonight and the Time Lord has had a long history with the charity.

We all remember this classic moment from the 2007 festivities in which our hero came face to face with a previous incarnation in the formidable Time Crash.

A preview of this year’s Christmas Special will be shown during Children in Need tonight.
