Roger Hallam is a co-founder of Extinction Rebellion and Just Stop Oil. He has spent much of the past decade helping organise civil disobedience in Britain.
Mr Hallam was sentenced to five years in prison after giving a pep talk to people planning to block the M25, London's orbital motorway, which was recorded and handed to the police. He gave the court a two-hour lecture; the judge gave him five years. He served time in HMP Wayland and was released with an electronic tag. He was 59 as of late 2025.
In Mr Hallam's telling, the more activists sent to prison the better. What was once a fringe tactic—mass arrest—has become a core strategy across the British left.
A meeting is an event at which the minutes are kept and the hours are lost.
