He used different personas to express his racist views and hatred of ethnic minorities and shared terrorist-related documents with others.

But he was arrested after Met Counter Terrorism officers linked the various online accounts to Nugent’s real-world identity.

He was sentenced earlier to three-and-a-half years imprisonment at Kingston Crown Court.

Commander Richard Smith, who leads the Met’s Counter Terrorism Command, said: "Nugent freely shared his abhorrent extremist views with others over a messaging app, and he passed on manuals detailing how to produce deadly weapons and explosive devices.

"However, he was stopped when he was arrested by counter terrorism officers.

"This is another case which shows how harmful online extremism is. That is why it is important that anyone who believes that they have a friend or loved one who they think has been radicalised, or is vulnerable, seeks help.

"The Counter Terrorism Command, with the national Counter Terrorism Policing network and other partners, work around the clock to bring the likes of Nugent to justice, root out harmful extremism online, and keep the public safe."

Nugent shared manuals on how to make explosives and homemade firearms, and published an edited video of the Christchurch Mosque terror attack. One of his offences relates to Nugent sending an edited version of the manifesto written by the Christchurch attacker.

Nugent was arrested in August 2020.

He was interviewed over seven days following his arrest, but gave no comment.

Nugent was initially charged with 12 Terrorism Act offences; a further six charges were subsequently added.
