police officers in the UK. Mair, however, appeared to have little involvement with National Action or any other white supremacist groups within the UK. Before it was banned, the organisation was the most active in Yorkshire, where half of the referrals to the government's anti-extremism strategy have been about the far-right. In October, the Jewish Chronicle reported that the organisation's leaflets "including swastikas, a Nazi salute and the phrase 'no tolerance'" were spotted in Hull, Liverpool, Glasgow and Cardiff. The Hull Daily Mail reported, "The first evidence of the group in the city was in July when graffiti appeared on a wall on George Street in the city centre with an incorrectly painted Swastika, the letters NA and a logo."

National Action is one of only four terrorist organisations based in Great Britain to be proscribed (one being the Sonnenkrieg Division, a splinter of the System Resistance Network (a National Action alias), and the other two being radical Islamist organisations). Its ban was seen as an acknowledgement by the UK government that the far-right
