UKIP leader Nigel Farage told BBC Radio Scotland's Good Morning Scotland programme:
The idea that UKIP is some kind of horrible, nasty, anti-immigrant, racist party is not something that was evident to the rest of the country, but of course that wasn't what it was all about.
It was a demonstration dressed up as being anti-racism but in fact in itself was deeply racist, with a total hatred of the English and a desire for Scotland to be independent from Westminster. I mean, my goodness me, if this is the face of Scottish nationalism it's a pretty ugly picture.
The anger, the snarling, the shouting, the swearing was all linked in to a desire for the Union Jack to be burnt and extinguished from Scotland forever. There's absolutely no doubt who these people were or what they stood for.
