If you look at their policies, they really are an ultra-capitalist authoritarian, hark back to the 1950s party.Of course, looking at their actual policies is difficult, since they completely disowned the last set and haven't quite come up with a new one yet. But a party whose spokespeople who come out with things like the the one above- plus the usual set of craziness such as "Climate change doesn't exist", "Over-regulation of the banks caused the recession", "Women should spend more time cleaning behind their fridges" and "All muslims should be asked to sign loyalty pledges" gives you an idea where they're coming from. On the political compass, they're heading straight for that top right corner.
Of course, the reason why this is gaining so much traction in certain parts of the UK is that these views are ripped straight from the pages of some UK newspapers. The Express and the Mail, and to a lesser extent, the Sun, the Times and the Telegraph (Yes, that's right- the newspapers owned by Rupert Murdoch are not the worst) have been banging on the drum of being anti-immigration ever since about 2001, when it became one of the few issues that the ruling,nominally centre-left Labour party were vulnerable on. And they've kept going all the time since then, providing a backdrop for the rise of UKIP, and worse.
