There is the bigger problem we do not yet have proportional representation in this country (which Denmark and most other European nations have). but even if we had it, going by the votes of the recent election, the two extreme right wing parties (the UKIP and BNP) would get much more seats than for instance the Greens. with regard to clamping down on nightlife and anti-social behaviour, Labour had a similar pledge in their manifesto and so did the Lib Dems (although not as harsh!). They were listed in a newspaper I got from CAMRA (an organisation for traditional British beer). The right wing parties of course had worse! In fact nearly every party did apart from the Greens.
However what also has happened in recent times in England as I mentioned elsewhere is that the people have been worse behaved in night time than ever before, and the previous Labour Government actually did alllow a lot more night time fun. Fighting, rapes, racist and homophobic murders, (this all in my town!) all because they people cannot handle their drink or drugs. It is much worse than most other European countries (apart from the ones where English tourists are common)
And not everyone what votes Conservative is teetotal – in fact the big breweries (the ones what make crap imitation of your countries lager) often fund the Tories a lot.
CAMRA (who actually were responsible for lobbying politicians for the late licenses) are keeping a close watch on this legislation to ensure venues are not unfairly targeted.
However, the Conservatives are planning to charge extra cost for each late night license over 23:30.
