Surrey Police said early this morning they were proactively patrolling the stretch of the M25 within their jurisdiction in anticipation of attempts to cause disruption.
The force said in an update on Twitter: “Keeping traffic moving is key & any criminality will be dealt with ASAP. If you’re delayed, pls don’t ignore ‘red crosses’ or use hard shoulder – this impacts emergency vehicles.”
At around 7am, traffic near Junction 8 clockwise closed after a protester was seen having climbed onto a gantry.
Another protester was arrested before they could climb, the police said.
The Metropolitan Police said on Twitter: “We’re ready to respond to any protest activity on #M25 with partner forces again today.
“We know this disruption is incredibly frustrating for the public.
“We will act as swiftly as possible to remove any individuals intent on obstructing the road and get traffic moving again.”
Just Stop Oil staged 32 days of disruption from the end of September and throughout October, which the Met said resulted in 677 arrests with 111 people charged, and officers working a total of 9,438 additional shifts.
According to Just Stop Oil, its supporters have been arrested nearly 2,000 times since its campaign began on April 1, and five are currently in prison.
