Protesters are taking over an annual property trade show to campaign against unaffordable housing in London.
The group is aiming to block roads around the Mipim conference to prevent Boris Johnson attending the event.
About 4,000 property delegates are expected to attend the show in Olympia.
The campaign group includes protesters against anti-gentrification, empty home protesters, unions and residents and aims to highlight the rising cost of housing arguing developers are pricing people out of the market.
The Mayor of London is set to make an opening address. Protesters are using #BlockBoris as part of the campaign.
