Activists, known as earth marchers, have been making their way in to central London for weeks for the 'International Rebellion'. And many have been encouraged to illegally camp in Hyde Park overnight in to tomorrow so they can 'come together, form relationships, consolidate plans, and gear up for the days ahead,' according to campaign group Extinction Rebellion. Climate protest group Extinction Rebellion set up camp in London's Hyde park ahead of plans to cause widespread disruption from tomorrow From Monday, thousands of people are expected to gather at Marble Arch, Oxford Circus, Waterloo Bridge, Piccadilly Circus and Parliament Square to block traffic during a three-day protest.

Those considering camping in Hyde Park have been warned they could be breaking the law, as doing so without permission is an offence under Royal Parks legislation. A spokeswoman for The Royal Parks says Extinction Rebellion have not asked for permission to begin the protest in the park and that camping is not allowed. She said: 'We never allow camping in the parks for reasons of safety, security, lack of welfare facilities and the impact it has on the park. It also removes public space from other park visitors. Police said their operational response 'would be dependent on what if any other issues might be ongoing at the time' Plans for the week of protests include wellbeing talks, training, entertainment and food 'Those camping in the parks are breaking the law. Enforcement of the park regulations is a matter for the Metropolitan Police.' Police said their operational response 'would be dependent on what if any other issues might be ongoing at the time'. Scotland Yard said they have 'appropriate policing plans' in place and that officers will be used from across the force 'to support the public order operation during the coming weeks'. They added: 'We will always provide a proportionate policing plan to balance the right to a peaceful protest, while ensuring that disruption to communities is kept to a minimum.

I am moved by this cause, by this moment in time that we have to make a difference.' Asked if she thought the Government will take notice, she said: 'I guess that depends how effective we can be in shutting down the city. 'It has to inconvenience them enough, it has to inconvenience the financial system, it has to inconvenience the tourist industry, it has to inconvenience the Government enough to recognise that they need to engage with this.' She said the disruption would mimic disruption they expect will be caused in the future by the effects of climate change and the destruction of the ecosystem.
