Proving you can't keep anything secret from determined Doctor Who fans, posters on Outpost Gallifrey's forum who've been watching the filming of the finale episodes of David Tennant's Doctor have spotted sit com and Carry On legend June Whitfield on set in Cardiff. No clues to who's she playing yet. Another member of the Noble clan perhaps? Or a new regeneration of the Rani? And, damn, now Daleks can fly we can't make some gag about her selling Stannah stair lifts to them.
