Several people have suggested Rory Stewart. Seems a nice sort of cove for a Tory.
... But, well, where did he go to school? And so what?
I have lived a life, which, for good or ill, brought me into contact with lots of the products of the, erh, expensive end of the English private school system, professionally and to some extent personally, socially, emotionally ...
There are certain attributes, I have found, shared by the alumni of the different schools. This is not a novel thought, by any means. Here's an old joke:
A Wykehamist, a Harrovian and an Etonian are at a party when a woman enters the room. The Wykehamist offers her a chair; the Harrovian fetches one; the Etonian sits in it.
-Be that as it may. In my experience - fairly broad, as I have said - you might have a good time with an Etonian; he will often be charming; but you certainly could never trust him as far as you can spit.
All Etonians? Maybe not. But a good rule of thumb all the same.
Sorry, Rory.
