Former Guantanamo Bay prisoner Moazzam Begg has said Donald Trump is one of the "bad dudes" who should be sent to the internment camp in Cuba.
Speaking from a stage in Parliament Square as part of the March Against Racism, Begg referenced a speech by the American president in which he said he would be sending more inmates to the controversial facility on the Cuban mainland.
He said: "The rise of the far right and the Nazis and fascists has seen a new wave with the election of Donald Trump, who said when he came to power, 'I'm going to load up Guantanamo with some bad dudes.'
"So my response is: 'When are you going, dude?"
Begg, a British Pakistani from Birmingham, joined Labour MP for Tottenham David Lammy in slamming a small group of counter-protesters.
Suspected to be from the far-right political group the English Defence League (EDL), the group were spotted near crowds of anti-racism marchers on their way from Regent Street to the foot of Parliament.
