Tom Kirby
Chairman and owner of Games Workshop. Forbes magazine described him as a "fucking tosser," which for those unfamiliar is akin to being called an unpleasantly diseased scrotum by Nurgle.
He continues GW's quest to make the game as commercial as possible and be as much of a dick to the devoted fanbase as possible. His reward thus far has been a company rapidly trending downward towards dissolution and irrelevance. There's a recurring theme of the media calling him a straight-talking person followed by him giving nothing but vague and/or evasive replies when he speaks, making it some kind of media in-joke.
Update: As of January 1st, 2015, Tom Kirby will be stepping down as CEO of Games Workshop[1]. The company's board of directors has decided to use Tom Kirby's "we recruit for attitude and not for skill" logic in order to find their next CEO, thus anyone interested in the position merely needs to apply for it. This likely entails the coming of a sea of rage and butthurt, as thousands of neckbeards are denied an interview. If a suitable candidate cannot be found, Tom Kirby's wife will probably take his seat as CEO. Yeah.
