Their website is just ghastly.
Their core policies seem to be pretty much the same of most other 'radical' parties (end immigration, leave the EU/NATO/whatever, economic nationalism etc though they are unusually keen on green issues).
I find the rhetoric on their site very grating though. It's true that there's always been radicals bubbling under the surface in England but to claim we've got a radical tradition of some kind seems awfully contrived, especially when you look at the continent.
On the other hand, it says they've only been around since July last year, so I kind of respect their ability to organise.
'What do you think of their idea of distributism'
I'm not sure I get it, actually. From what's on the site, it seems to want to ignore globalisation and wish it to go away. I don't think that's as practical as they make it out to be.
