Insulate Britain protesters have blocked Old Street roundabout in central London and a junction of the M25 motorway, as they continue to disrupt major roads despite being served with an injunction against road-blocking demonstrations.
The climate activists said about 40 demonstrators are sitting on the road at junction 25 of the M25 at Waltham Cross, Hertfordshire, and at the Old Street roundabout.
In a video posted on social media by radio station LBC, protesters can be seen lying in front of a police car on the M25. Officers then drag some of the activists off the road.
The protests on Friday morning caused long queues of rush hour traffic, with furious drivers calling the demonstrators "selfish".
The group posted a video on their own social media channel, saying their policy "has always been to move out of the way for emergency vehicles with ‘blue lights’ on", as a video shows an ambulance driving past with sirens and blue lights on.
This is the 12th day in the past four weeks that the group has carried out protests on roads.
Insulate Britain admitted its actions on the M25 are “in breach” of an injunction obtained by the government last month.
Tracey Mallagan, a spokeswoman for the group, which is calling on the government to insulate all UK homes by 2030 to cut carbon emissions, said: “If governments don’t act soon to reduce emissions, we face a terrifying situation.
“We won’t be worrying about shortages of pasta or loo rolls because law and order breaks down pretty quickly when there is not enough food to go round.
“The government won’t be wondering if there are enough hospital beds or ventilators, but whether there are enough people left to bury the dead.
“The government is destroying our country. Boris Johnson should be taken to court for treason. Our flesh and blood are being tossed aside as expendable.”
