The UK used to be a two party system...we appear to be breaking out of that by stages. It is fair to say, and the newspapers have repeated it
ad nauseam, that we are a 3 party system (Labour, Tories, Lib Dems). I see no particular harm in this. Let's have a system by which we are not bound by Eeny or Meeny - let's have genuine ideological differences and a competition of ideas.
