Police have revealed more than 100 people were arrested on Waterloo Bridge last night and this morning as climate change protesters failed to abide an order allowing them to only congregate at Marble Arch.

So far, 122 people have been held as part of the ongoing Extinction Rebellion (XR) demonstrations, the majority of which were for breaching a public order offence and obstructing the highway.

The XR group yesterday targeted Marble Arch, Oxford Circus, Waterloo Bridge, and Parliament Square in a series of road blockades, which it warned could last for weeks.

Police chiefs said they decided to impose an order last night stating activists could demonstrate within the Marble Arch area following "serious disruption" to businesses and public transport.

Chief superintendent Colin Wingrove, from the Metropolitan Police, said 55 bus routes had been closed as a result of the blockades, which has affected half a million people.
