Drivers on the M25 travelling through Buckinghamshire are experiencing severe delays due to protesters on the motorway.

The road has been closed in both directions between Junction 15 and Junction 14, with southbound traffic tailing back to Junction 16, where traffic from the M40 joins the M25.

Thames Valley Police has warned that the Just Stop Oil protesters are expected to remain in place for several hours, and have advised motorists to seek a different route.

Highways England has advised that traffic is tailing back five miles in both directions.

Images taken from the scene show that protesters have climbed up the motorway gantries that support overhead motorway signs.

Motorists stuck in the jam have been left furious.

Bus driver Ashley Reid takes special needs children aged seven to 10 to a school in Leatherhead by travelling between junction 12 and 10 and said his pupils, who start at 9.15am, were around 90 minutes late for their last day of term as a result of the disruption.

“We joined (the motorway) just after 9am and we didn’t arrive at school until 10.45am… with their autism (they) found it difficult to understand and stay calm,” the 40-year-old said.

“It was really disruptive and I felt so sorry for them… today was their last day before the summer break and they would all be changing classes so they just wanted to get to school and spend time with their teachers and friends.”

The children are set to finish school at 1pm, when Mr Reid will have to return to the school to pick them up.

“I am sympathetic to the cause that these people are protesting against; however, they are disrupting a lot of innocent motorists and (in my opinion) will lose more sympathy than they gain,” he added.

A spokesman for Just Stop Oil said: “The main thing is, we’ve just seen 40 degree temperatures, which have been predicted for decades, maybe it’s happening a bit faster. But it has just revealed how inadequate the Government’s preparations for climate change are and their entire policy, and basically we’re just saying it’s evident now we cannot continue.

“As we’re going on, we need to stop new oil. It’s the first step to ensuring we have a liveable future, and maybe it’s already too late.

“This is something we definitely need to do.”
