Knee-jerk slogans like "nanny-state government" don't really add up to much. If the implication is that this government is particulary anti-liberatarian, and that the Tories would be the other way round, that's a little bit implausible.

I can't see how legalising 24 hour drinking and casinos, and down-grading the penalities against people who smoke grass are particularly nannyish. I can't see how opposing such measures is particularly libertarian.
