Patrick Troughton. Had the toughest job of the lot in being the second Doctor. A role in which he successfully paved the way for all of those who've followed since.
Which is why I've voted for him.
There have been many excellent actors who've successfully played the role. Ranging from Jon Pertwee to Matt Smith.
But as for the next doctor. I have to admit I don't know if this is anything to do with the BBC's obsession with it's LGBT/PC agenda or whether it's simply a case of inspired genius. Only time will tell.
