Thanks! That makes sense.
I found this article which lays bare the sheer number of Oxford and Cambridge graduates in the Tory and Labour parties at Westminster.

It's a shame they don't break it down by subject studied. (I'd hypothesise that most of the Oxbrige MPs have humanities degrees, which in turn might explain why so many Oxford graduates end up in politics? )
The bit that jumped out at me: "...10 MPs graduated from a single college, Balliol in Oxford. [7 CONs 3 LABs]...".
It's got a bit of a "To the Manor Born" architectural vibe?
