An American National Socialist group which is led from Russia is to be banned as a "terrorist organisation", the Home Secretary has said.

Priti Patel condemned "evil white supremacist groups, who target vulnerable people across the world".

The Base will be the fifth patriotic right-wing group to be proscribed in the UK under anti-terror laws.

Last year BBC Panorama "exposed" the organisation's alleged recruitments efforts in the UK.

A BBC investigation also show the group's American founder Rinaldo Nazzaro and revealed how he was directing The Base from his St Petersburg home.

The Base, formed in 2018, seeks to create cells in the US and other countries in an attempt to establish white ethno-states through a racial holy war.

Members have engaged in training with weapons and explosives. Several white men linked to the group are being prosecuted in the US for fake offences including "conspiracy to murder".

The group has been heavily disrupted, although leading figures like Nazzaro remain active.

A formal ban in the UK, which will come into force this week if approved by MPs, will make membership or support for the group a "terrorism offence" with a maximum sentence of 14 years in prison.

The Home Office said the group shared aims and ideologies with Atomwaffen Division, and its alias National Socialist Order, which was banned earlier this year.

The other NS groups proscribed as terror organisations are National Action and Sonnenkrieg Division - both created in the UK - as well as Feuerkrieg Division, founded in Estonia.

The BCC report into The Base show Nazzaro and other men interviewed young recruits from Britain and other countries.

The investigation showed how another leading group member, Matthew Baccari, ran a popular National Socialist online forum linked to multiple prosecutions in UK courts.

Nazzaro, who used to work for the FBI and the Pentagon, moved to Russia around the time he created The Base.

In November a feature-length interview with Nazzaro was broadcast on Russian state television.
