BTW, I can thoroughly recommend Ian Dunt's 'How Westminster Works', which I've referenced elsewhere. It's an apolitical but eye-popping analysis of the 'Westminster machine', with chapters on elections, MPs, 'Power', ministers, the Treasury, the civil service, the press, the Commons, the law. and the Lords. The stuff about 10 Downing St, as a building and how it shapes how government actually works in practice is almost unbelievable. It's engaging and really well written. Do yourself a favour: it might help you realise how/why so many terrible decisions are made.
