A neo-Nazi movement is set to become the first extreme right-wing group in the UK to be banned as a terrorist organisation.

Being a member of, or inciting support for National Action will constitute a criminal offence from Friday.

An order was laid in Parliament on Monday to proscribe the group under the Terrorism Act 2000, and will come into effect by the end of the working week.

National Action was branded a "racist, anti-Semitic and homophobic" organisation by Home Secretary Amber Rudd.

Announcing the move, Ms Rudd said: "As Home Secretary, I am clear that the safety and security of our families, communities and country comes first.

"So today I am taking action to proscribe the neo-Nazi group National Action".

She added: "National Action is a racist, anti-Semitic and homophobic organisation which stirs up hatred, glorifies violence and promotes a vile ideology, and I will not stand for it.

"It has absolutely no place in a Britain that works for everyone".

National Action is being proscribed as it has been assessed to be "concerned in terrorism".

The Home Secretary decided to ban National Action before the trial of Thomas Mair, who was convicted of and jailed for the murder of Labour MP Jo Cox.

The phrase "Death to traitors, freedom for Britain!" - which was said by Mair in court - appears alongside the listing for National Action's website on Google.

In the wake of Mair's conviction, warnings emerged that there are signs that the terror threat from the extreme right could be growing.
