Jeremy Corbyn protested against the extradition of British terror suspects to the United States as Anjem Choudary, a mentor to the London Bridge attacker, led a rally for the same cause just yards away.

The Labour leader spoke outside the Royal Courts of Justice in 2012 before Moazzam Begg, a former Guantanamo Bay detainee who appeared to argue that five men, among them the notorious hate preacher Abu Hamza, should not be deported.

Two of the men were aides to Osama bin Laden wanted in connection to the 1998 bombings of the US embassies in East Africa, whilst the other pair later pleaded guilty to providing material support for terrorists.

Speaking just hours before High Court judges dismissed the final appeal of the five men against extradition, Mr Corbyn told the gathering: “We are fighting against the overwhelming power of the USA to extradite people from this country.”

Photographs and video footage taken at the event in central London show Mr Corbyn standing next to Asim Qureshi, the Cage UK spokesman, who in 2015 described Mohammed Emwazi. the Isil terrorist, as a “beautiful man”.

Just 30 yards away, Choudary, the co-founder of the British terror group Al-Muhajiroun, was also protesting at a second demonstration against the extraditions along with Siddartha Dhar and Mohammed Reza Haque, two men who would later become “poster boys” for Isil.
