The U.K. is generally left of the U.S. JFK once quipped to Harold Wilson that he was lucky that his (Wilson’s) lunatic fringe was on his left. Kennedy, of course, had the Birchers to deal with.
This being said, the Conservative party in Britain occupies the same general space in their political spectrum as the Republicans do here, but their society in general is different enough from ours that you can’t make a direct comparison. The structure of their government is greatly different from ours as well. The new government there could, for example, dissolve at any time and may well do so if the coalition between the Tories and the LDs falls apart (as it’s expected to). Not having predictable terms and election cycles for politicians gives the country a very different political landscape.
