Campaigners climbed on top of a train and glued themselves to the roof during a third day of climate change protests, which have caused serious disruption in London.

Two Extinction Rebellion demonstrators clambered aboard the carriage of a DLR train at Canary Wharf station in east London at around 11am on Wednesday.

Later in the day protesters gathered outside the north London home of Jeremy Corbyn. One of the demonstrators chained herself to the leader of the Opposition's garden fence with a bike lock.

More than 300 protesters have already been arrested this week following protests across central London.

Activists are demanding the government declare a climate emergency and reduce greenhouse gas emissions to zero by 2025.
