It's a difficult question. British Prime Ministers in general are reprehensible bunch. Adulterers, slave traders, liars, war mongers, racists. In short, just the type any decent person wouldn't want as a family member. In my own lifetime, Thatcher was awful. Anyone who could cut cash which went into the research of cot-death syndrome has to be among the lowest form of life. Blair was also awful. People thought he would make things a little easier for the working class, but the change over from the Tories was almost seamless. Atlee was probably one of the best, but his record on foreign policy was not a good one, but probably all anyone could expect from a man of his class.
