Highbury Corner tunnel built by same crew behind HS2 protest tunnel at Euston, say environmentalists
A second tunnel or tunnel network has been occupied by tree protectors in central London in protest at plans by Islington council to fell a range of six mature trees to make way for new housing.
Activists from a group called Save The Trees are occupying the site, which is close to a busy roundabout in a polluted part of London.
