Mark Rowley said that police continued to investigate the activities of the far rightAndy Rain/EPA

On two occasions this week the UK’s top counterterrorism police officer has publicly voiced his concerns about the possible threat from the far right.

Mark Rowley, a Metropolitan Police assistant commissioner, inevitably focused on Islamist terrorism after four attacks this year, but he also made it clear that police would be unwise to discount neo-Nazi extremists.

Resources have been diverted from investigations into war crimes and domestic extremism so that police can focus on disrupting Islamist plots but detectives have kept up their investigations into the “very concerning” activities of the far right, Mr Rowley told the home affairs select committee.

He repeated his concerns the next day at the National Security Summit, speaking alongside Sue Hemming, head of the Crown Prosecution Service counterterrorism division.
