ANTI-HATE groups and police warned of an increasing threat of right-wing terrorism and extremism after yesterday’s conviction of neonazi Thomas Mair for the murder of MP Jo Cox.

Mr Mair shot and stabbed the Labour MP for Batley & Spen in West Yorkshire on June 16, a week before the EU referendum.

The Old Bailey jury heard how he shouted: “Britain First” as he attacked the mum-of-two outside her constituency surgery.
