A far-right extremist who made a speech at an anti-Jewish demonstration in London and posted more than a hundred racist comments on Facebook has been sentenced to four years’ imprisonment.

Lawrence Burns, 23, was convicted of stirring up racial hatred at a trial at Cambridge Crown Court in December 2016.

The trial heard Burns had referred to Jewish people as “sub-human animals” on Facebook and in another post said he wanted to “hang the black race”. He also expressed admiration for Adolf Hitler.

Deborah Walsh of the Crown Prosecution Service said: “Lawrence Burns advocated extreme racial violence and hatred through both speaking in public and from behind his keyboard.

“The prosecution put forward compelling evidence detailing Burns’ abhorrent views which left the jury in no doubt he was guilty of stirring up racial hatred.”
