On 23rd April, in Whitehall, London, Mark Campbell held up a very large PKK flag, to make a political statement against the continued criminalisation by the UK Government of the Kurdish community and the whole Kurdish issue in Turkey and the Middle East.

On 27 October 2022, he received a letter informing him that he was being charged under Section 13 (1) and (3) of the United Kingdom’s Terrorism Act 2000.

The new hearing will take place on 13 September. Campbell said: "On Wednesday the 13th September I will be on trial charged under the UK's Terrorism laws for my support of the Kurdish people's freedom struggle. The Kurds have been the victims of Turkey's state terror for one hundred years. I am proud to stand with the Kurdish people."

Talking about the day of the alleged crime, Campbell said: "Dozens of police blocked off the road in front of our peaceful demonstration as it came into Whitehall and senior officers sent ‘snatch squads’ into the crowd in a pre-planned operation to aggressively target and seize people whom they had identified as holding a flag."
