Protesters are causing widespread disruption on the M25 for a second day after several junctions were blocked.
Essex Police said officers are on the northbound carriageway of the UK’s busiest motorway near the Dartford Crossing, where a demonstrator, believed to be from Just Stop Oil, has climbed the gantry at junction 31, closing the Dartford Tunnel.
National Highways said there are currently delays of 60 minutes, with congestion for five miles.
