Angry motorists covered Insulate Britain protestors in INK today (Weds) as they returned to London's roads during rush hour.

The activist were seen with blue on their clothes and faces as they started blocking the A40 and M25.

A Metropolitan Police spokesman said: ''The Met is aware of Insulate Britain activists blocking the road at the A40 junction with Gypsy Lane in North Acton.

''Officers were promptly on the scene. Traffic has had to be diverted for the safety of all. We'll share updates soon."

The protests follow Insulate Britain's warning to the public not use the M25 this morning that they issued yesterday, while also asking the public to reduce their speed on the vital road to 20mph.

Using a strategy of gluing themselves to the road on their hands, faces and feet, the activists aim to become more difficult to remove in fresh protests.
