Campaigners from the group Insulate Britain have blocked the Port of Dover as part of their protests over climate emissions.

More than 40 people, who have been involved in Insulate Britain’s 10 days of motorway protests, blocked the A20 at the eastern docks roundabout and near the junction with Union Street for the western docks, the group said on Friday morning.

A spokesperson for Insulate Britain said: “We are sorry for the disruption that we are causing. It seems to be the only way to keep the issue of insulation on the agenda and to draw attention to how poorly insulated homes are causing ill health, misery and early death for many thousands of people.

“We are failing the country’s cold hungry families and the elderly and placing an enormous burden on the NHS.

“Insulating our leaky homes is one of the most cost-effective ways to reduce carbon emissions and it has all these additional benefits – reducing fuel poverty, creating jobs, reducing the burden on the NHS and protecting people from overheating during future heatwaves. It’s a no-brainer. Boris just needs to get on with the job.”

The Port of Dover said in a statement: “Port of Dover confirms protesters are currently blocking the entrance to the port.

“Please allow extra time for your journey and check with your ferry operator for updates. The port remains open.”
