The comparison with Communism is very correct, but even those didn't arrogate such powers as the current police state can do. Actually disappearing the dissidents was very hard for them to do, it's not a problem in Britain nowadays with the police being able to detain anyone on a whim.
Also the idea that the monarchy has no grip over politics - it's about the real power, things like money and connections. If the other european countries had never thrown out their monarchies, they would be as backward as Britain today.
It's on this kind of background that a movement like the BNP can run these things, or where else do you find that kind of action in Europe? Oh right, the "new Europe" in the east also have these fascist militias training kids.
I think the modern policestate is already there with CCTV and the genetic databases, neighbourhood spies and all these things.
There are two things missing in the UK for a police state.
(a) respect for "authority" - we have possibly one of the most disrespectful societies there is;
(b) the slightest degree of competence - our current government is as divorced from reality and truly dysfunctional as it is possible to get in the developed world. "Any economic unit can emit money. The serious problem is to get it accepted" Hyman Minsky
