The House of Commons has been called "the best club in London", but only by people who aren't members of any others. For it lacks the key ingredient that makes up a really good club: the blackball. Absolutely anybody can become a Member of Parliament who has the qualifications of a thrusting temperament, opinionated nature, desire to boss us about, need to show off and, very often, a gnawing inferiority complex and mother fixation. Who would want to belong to a club full of people like that? And that was before we discovered they also had their fingers in the till.
