The honours list got me looking up who is actually in the HoL. They mostly seem to be ex politicians or their aides with a random smattering of business people (ownership class), journalists, artsy types, and Ian Botham. I only got as far as C before i got bored.
One business guy apparently runs a private equity firm, with £20m invested - about the smallest PE firm i've ever heard of. On further inspection, it's the biggest investor in Samantha Cameron's company. I'm sure that's not why her husband appointed him though.
I'd like to see a breakdown of the members by their area of expertise. I'm willing to bet that lawyers outnumber scientists, bankers and other financial engineers outnumber social scientists and actual engineers, and parasitic hangers on outnumber useful humans.
