Protesters stop traffic at Hanger Lane, the Blackwall tunnel and Wandsworth Bridge
Insulate Britain activists have staged three morning roadblocks in central London, leading to dozens of arrests and confrontations with drivers stuck in heavy traffic at the height of rush-hour.
The climate activist group said 54 supporters had blocked Hanger Lane in north London, the Blackwall tunnel in south-east London, and Wandsworth Bridge in south-west London, as they began a fourth week of their campaign for government action on home insulation.
