New Doctor Who to be announced
The BBC will announce who the new Doctor Who will be after the current Doctor gives up the roll.
Scottish actor David Tennant will record another four special episodes in 2009.
His replacement - the eleventh Doctor of the TV series - will be revealed in a Doctor Who special programme on British TV on 3 January.
The name of the actor who will replace David Tennant in Doctor Who will be announced on Saturday.
Tennant said in October that he would stand down from the show after filming four special episodes in 2009.
His replacement - the eleventh Doctor of the TV series - will be revealed in a Doctor Who Confidential programme on BBC One at 1735 on 3 January.
The casting was confirmed over Christmas and filming for the 2010 series begins in the summer.
Tennant is due to begin shooting the first of his four specials this month, just weeks after surgery on his back.
