The man prepared to go to prison to save Sheffield's trees
Thousands of trees have been cut down in Sheffield as part of the council's £2bn 25-year Streets Ahead project, which is being carried out by contractor Amey.
Protesters have been arguing that many of the felled trees were healthy.
We follow Calvin Payne, convicted tree protester, who could potentially go to jail for preventing the council from cutting down any more trees.
