Climate Camp descends on London today with the police promising to take a low-key approach to the climate change protests to avoid the trouble that flared during the G20 summit. Follow live updates from our reporting team as they follow developments across the city.
Up to 3,000 protesters had gathered at different meeting points across the capital before their final destination was announced by text message and on Twitter.
The group will pitch their tents in the park and intend to remain there for a week.

Peter Walker at Blackheath says there are around 100 protesters at the site of the main camp. Some protesters are now on top of tripods erected with scaffolding on the heath. These are put up by protesters to prevent them being moved on by the police - as they can't be dismantled without the risk of injury to the occupants. Peter can also see a load of trucks and a coach, but no police.
EDIT: 3.02pm: Peter Walker says the first police have arrived at the camp. There are now 500 protesters on site including 6 on tripods - at least one of which is being extended to 25ft high. He has also spoken to a Blackheath local for her view of the camp. She says: "I believe in the action they're taking against global warming but I'm not sure about this anti-capitalism."
