A police say all six accused had been charged with being a member of a proscribed organisation contrary to section 11 of the Terrorism Act.
National Action were banned as an organisation in December 2016.

What is a proscribed organisation?
An organisation that the Home Secretary believes is concerned in terrorism can be proscribed under the Terrorism Act 2000 if it is proportionate to do so.
This means that the organisation commits or participates in acts of terrorism, prepares for terrorism, promotes or encourages terrorism or is otherwise concerned in terrorism.
When deciding if it is proportionate to proscribe an organisation, the Home Secretary will consider several factors, including the nature and scale of its activities, the specific threat it poses to the UK and British nationals overseas and the extent of its presence in the UK.
The Home Secretary can issue an order that an alternative name or alias is to be treated as another name for a banned organisation.
