On sales and skills Liz beats Stuart hands down, she proved that throughout the series. Stuart talks the talk but cant walk the walk. He's all hot air, so why did Lord Al full for all that crap he was spouting in the board room.

Stuart is a clown and a very good talker thats it.

I suspect he's been allowed through to be thoroughly roasted during the interviews.

I think that Liz's failure to fight her corner in the Boardroom was the reason why she was sadly fired. In other words, too nice a person for the Apprentice job.

Margaret Mountford will easily prick the prick that is Stuart and let all the hot air out.
