Almost 100 people rallied outside Holloway Women’s Prison in solidarity with jailed protesters on New Year’s Eve.
The “noise demonstration” was organised by Defend the Right to Protest and the Legal Defence Monitoring Group.
Supporters chanted and banged pots and pans to make sure they could be heard inside
There was also radical hip‑hop, and speeches from the relatives of imprisoned students including Zenon Mitchell-Kotsakis of Sussex university.
Since the student protests of 2010 and the riots of August 2011, thousands of young people have been targeted.
Some have been given long custodial sentences, meaning they spent the festive period away from their friends and families.
Defend the Right to Protest is calling on supporters to write to imprisoned protesters.
Frank Fernie was jailed last year for throwing two placard sticks in the direction of police on 26 March. He said, “The support and mail I received when I was in prison was absolutely great and really kept me positive.
“I would encourage anyone who has something helpful or supportive to say to political prisoners to write to them.”
