A Halloween trick, not a treat.
David Tennant is to stand down as Doctor Who, after becoming one of the most popular Time Lords in the history of the BBC science fiction show.
Tennant stepped into the Tardis in 2005, and will leave the role after four special episodes are broadcast next year.
He made the announcement after winning the outstanding drama performance prize at the National Television Awards.
“When Doctor Who returns in 2010 it won’t be with me,” he said.
