edit: oh lol I get it now, in the post I replied to you're doing a very literal interpretation of "they all went to the same schools" and refusing to interpret this as it's very clearly intended (that a huge amount of MPs went to a couple of schools)

30% of our House went to a top 100 university which isn't necessarily saying much - that list includes many state universities and I'd say that's a perfectly appropriate number.

20% of the British Parliament went to Oxbridge alone.
