What an idiot!

No, it's self inflicted.

That was a classic instance of

Step 1 Open mouth
Step 2 Insert foot.

It is of course nothing to do with the old boys network is it, the number of old Etonians in the higher echelons of the tory party. Nothing whatsoever. They just turn out a better sort of self-sacrificing chap.

Chaps, of course, is the operative word JessM. Girls aren't really up to that sort of thing.

It could also of course be in Eton that they teach people the necessary skills to shout other folk down in the Oxbridge debating areas and beyond?
Or that their daddies can afford to fund them indefinitely while they work as unpaid political interns when they leave Oxbridge?
