CEP Senior Advisor Ian Acheson writes: "Neo-Nazis are the fastest growing cadre of violent extremists in our prisons, and now yet another offender motivated by far right ideology has entered our creaking jail system. Last week, Andrew Dymock was jailed for seven years for terrorist offences. Earlier this year Dymock, 24, was found guilty of multiple charges of encouraging and fundraising for terrorism. He was also convicted of possessing and disseminating terrorist material."
