Video report by ITV News Social Affairs Editor Penny Marshall
Extinction Rebellion (XR) climate activists have vowed to continue to occupy four main sites in London overnight after a third day of protests.
Police have made 340 arrests over the past three days of protests, most of them for demonstrating in areas where a restriction is in place, including Waterloo Bridge, Parliament Square and Oxford Circus.
Activists, who are demanding a meeting with the government, said they plan to continue their roadblocks, which have affected more than half a million people with road closures, traffic gridlock and disruption to transport and businesses since Monday, until at least next Friday.
XR say direct action is needed to force authorities to act urgently on climate change and wildlife declines and halt a "sixth mass extinction".
Earlier, two men and two women had used glue and a bike lock to prevent police removing them from outside Mr Corbyn's house before leaving of their own accord and apologising for "upsetting" his wife, Laura Alvarez.
It was the latest development on the third day of demonstrations which has seen 340 arrests.
