The man who organised the student protest against Nigel Farage during his visit to Edinburgh has defended the action as "constructive criticism".
James Moohan said UKIP's policies would disproportionately affect Scotland, and also criticised Mr Farage for calling a female student "sweetheart".
UKIP MEP Roger Helmer said Mr Farage, who called the protesters "fascist scum", was "perfectly entitled to respond in a robust and forthright way."
