A man from Lancashire who played a key role in organising the Dover protests has been jailed for two-and-a-half years for violent disorder.
Shane Calvert, 34, of Shadsworth Close in Blackburn, rallied supporters to take part in a march through the town on Saturday, January 30.
A counter-protest was held at the same time and both sides quickly engaged in violence towards one another.
Calvert was filmed throwing debris, pushing against the police cordon and standing on a police vehicle during the disturbance.
He was arrested at his home address on Monday, March 7 but denied a charge of violent disorder.
A jury at Canterbury Crown Court returned a guilty verdict on Thursday, September 22.
Detective inspector Bill Thornton said: “While everyone involved in the violence was responsible for their own actions, Shane Calvert played a big part in bringing groups of troublemakers together in one place.
“He has considerable influence over those who share his political views and has a lot to answer for following the wholly unacceptable behaviour witnessed in Dover last January.
“I am very pleased the courts have recognised this and imposed a lengthy prison sentence on Calvert, ensuring he will no longer be able to stir up trouble and bring further harm to other communities throughout the UK.
“The investigation into offences committed on the day continues and I am confident there will be many more positive outcomes for the people of Dover.”
