Eleven people have been arrested across England and Wales as part of an investigation into the banned extreme right wing group National Action, Greater Manchester Police said.
Specialist counter-terror officers from across the UK swooped to detain 11 men aged between 22 and 35 in a coordinated action, the force said.
Five of the suspects were held on suspicion of preparation of a terrorist act, while one was accused of possessing terrorist materials.
One of those arrested over their alleged participation in a terror plot was produced from prison.
Six came from the North West of the UK, two were from South Wales, two were from West Yorkshire and one came from Wiltshire.
Eleven properties are being searched across a number of force areas in England and Wales.
National Action was banned in the UK in December 2016 as an extremist group.
The arrests follow activity earlier this month by West Midlands Counter Terrorism Unit.
Neil Basu, the Senior National Coordinator for Counter Terrorism Policing, said the action had resulted from two separate investigations.
Counter-terrorism policing is committed to tackling all forms of extremism that threatens public safety and security.
"Investigations relating to alleged extreme right wing activity are pursued with the same level or resource and vigour as other ideologies, in order to bring suspected offenders before the courts."
