Three men, including two British soldiers, accused of being members of a banned neo-Nazi group, will stand trial in March.
Lance Corporal Mikko Vehvilainen, 32, Private Mark Barrett, 24, and Alexander Deakin, 22, are accused of membership of National Action.

Mr Deakin, from Great Barr, Birmingham, faces further charges of distributing a terrorist publication and possession of documents likely to be useful to a person preparing to commit an act of terrorism.

- Possession of pepper spray
