Climate change activists stage tattoo protest against BP at Tate Britain

Thirty-five protesters occupy 1840s room at London gallery two days before UN climate change talks open in Paris

Climate change activists have occupied part of Tate Britain, where they have started to tattoo each other in protest at BP's sponsorship of the gallery.

Tate has closed the 1840s gallery where 35 activists have set themselves up and started to tattoo each other with the numbers of the CO₂ concentrations in the atmosphere in the year they were born. They estimate it will take all day to complete the tattoos.
