Several protesters who took part in student demonstrations last year were set to be sentenced in Kingston crown court on Thursday of this week.
They include Strathclyde University student Bryan Simpson. He is charged with violent disorder.
Defend the Right to Protest has called a protest at the court for 10am on the day.
Happy Birthday Ed
