From having lived in several countries in Europe, including the UK, I would say that Britain is the closest we have here to the US when it comes to being a deeply flawed Democracy, possibly worse than the US since unlike it, Britain doesn’t even have a written constitution, so just about everything can be changed with a law passed by a simple parliamentary majority (of 50% + 1) and as the UK has a First Past The Post electoral system said majority can be had with a mere 34% of votes cast (the current government has such a parliamentary majority with only 33.7% of votes), which given the typical level of Parliamentary Elections abstention over there is less than the votes of 1/4 of voters.

Britain has wonderful propaganda helped by some really weird elements like the local elites sending their children to schools were they learn the fine arts of “managing apperances” (learned behaviours which in many other countries would be considered dishonest and deceitful) plus a media industry which is World class (probably the best Theatre industry in the World, IMHO) often used to project a very good image of the country (its almost a joke how every couple of years, almost like clockwork, out comes a new film about WWII portraying Britain as a great country), so from the outside most people have a good impression of of that country, but if you’re living there and get involved in Politics and really learn about their system, the more you learn the less Democratic it seems.
