What is a Liberal ?

Not a left-liberal, not a classical liberal just a liberal. The UK Liberal Democratic Party (not the US Democratic party) is the oldest political party. They have been consistently (relatively) resistant to the concept of a party line (note liberals don't like the concept of a party line). It is very hard to decide what they believe. I would very roughly define liberal doctrine as follows: If John Locke and Charles Kennedy agree on something it is a core principle of liberal doctrine.
