Protest comes after court injunction threatened fines or imprisonment for demonstrators
Activists of Insulate Britainblocked a roundabout at a junction with the M25 by glueing themselves to the road on Wednesday morning.
The protest, which started at about 7.30am, is the seventh similar action to be taken by the Extinction Rebellion splinter group – and the second since the granting of a court injunction that threatened imprisonment or unlimited fines if they did not stop.
