It seems to me that Bercow’s “two fingers up at the establishment” is probably at least partly a reaction to years of traditional nonsense about how the wife of a successful man in the public eye should behave. I did agree with Ros Coward‘s comment that there are better ways to “prove women are independent and successful in their own right” but -gender aside- I’d suggest the expectations placed on the partner of a powerful person tend to serve to reinforce traditional power relations, where one partner is seen as the leader out in front and the other is expected to know their place.
That said, it’s certainly easy to criticise Big Brother. I have to admit I don’t watch it anymore, unless I’m going to write or talk about it, as the general baiting and editing of the contestants is often so painful to watch. (As Steven Nolan pointed out, they’re all vulnerable in there.)
