Page 3 was brought up at the Levenson enquiry and the editor of The Sun trotted out a tired old defence to what is a tired and dated section of the newspaper.
It was described as an institution. Not all institutions are worth preserving though. It perhaps should have followed that other "institution" Miss World and disappeared (from UK screens, at least).
That it hasn't suggests a large number of readers of The Sun and Daily Star enjoy it, though its debatable whether it is the deciding factor to buy said publications, The Sport had an abundance of nipples and very little else, which didn't save them from going bankrupt (or bust, if you forgive the pun).
Do I support a ban? No, I am not a fan of censorship, if you believe there is something worth censoring, I do not consider breasts pornographic and the same goes for bottoms, in my opinion. But then I'm probably out of step and enthused with too much western European liberalism. The participants are adult, consenting and paid and there are more trubleing and sexist images appearing on celebrity websites and magazines everyday.
