Ah, Tommy Robinson. Only a former leader of the EDL could manage to provoke violence at a book signing. And only a former leader of the EDL would think that the best place for such a literary event would be in an off-licence in Sunderland.
Incredible to think, isn't it, that apparently Robinson is literate? That said, I suspect that the book was ghost-written and that he was just signing his name with a big cross prior to being rudely interrupted by the sort of mindless thuggery of which he's often proud.
