Four British soldiers have been arrested on suspicion of being members of a neo-Nazi terror cell.

Police announced that they took four men into custody — three in their twenties and one aged 32 — on suspicion of being part of the far-right National Action group.

National Action recently became the first right-wing organisation to be officially banned by the government, which means that being a member of the group is itself a terror offence.

It was outlawed in December 2016 by Home Secretary Amber Rudd, who has the power to ban groups under UK terror laws. At the time she said: “National Action is a racist, antisemitic and homophobic organisation which stirs up hatred, glorifies violence and promotes a vile ideology.
