A National Socialist group is to become the second nationalist group to be banned as a terrorist organisation in the UK, the home secretary has announced.
Sonnenkrieg Division (SKD), members of which have been jailed for "serious offences", is to be proscribed, making membership of the group illegal and punishable by up to 10 years in prison, Priti Patel said.
Another order will recognise the right wing group System Resistance Network as an alias of the already proscribed National Socialist organisation National Action.
Two teenage members of SKD, Michal Szewczuk, 19, from Leeds, and Oskar Dunn-Koczorowski, 18, from west London, were jailed for "terrorism offences" in June last year.
The pair encouraged an attack on Prince Harry, who they referred to as a race traitor for marrying Meghan Markle, a woman of mixed race, glorified the Norwegian shooter Anders Breivik, and said white women who date non-white men should be hanged.
The orders come less than a week after nine people with non-white immigrant backgrounds were murdered in the western German city of Hanau by Tobias Rathjen, a 43-year-old who had posted a nationalist video and manifesto on the internet.

Patel said: "Recent attacks here and in Germany have highlighted the threat we continue to face from violent extremism. We are working to keep the public safe by increasing funding for counter-terror police and strengthening the law to keep terrorists locked up for longer. By proscribing these groups we are making it much harder for them to spread their hateful rhetoric."
This decision follows a meeting of the Proscription Review Group, which brings together representatives from the police and other partners to assess the risk posed by groups that may be considered for proscription.
SKD is the UK arm of the National Socialist Atomwaffen Division formed in 2015 in the southern US. It emerged in 2018 around the time of the arrests of Szewczuk and Koczorowski.
The move to ban SKD comes amid evidence suggesting patriotic violence is on the rise across the UK.
Senior counter-terrorism officials have warned that the "far right poses the fastest-growing terrorist threat in the UK".
