A freeclimber dubbed "Spider-man" has scaled the Lloyd's of London building to protest against climate change.

Frenchman Alain Robert climbed the City of London landmark without ropes and unfurled a banner warning of "100 months" to save the world. Onlookers said he leapt out of a silver car that pulled up outside One Lime Street just before noon on Friday and began his ascent, without ropes, on the Leadenhall Passage side of the building.

He reached the 9th floor of the 290ft-high building and unfurled a yellow banner before climbing down to street level, where he was met by police and led away. Robert has conquered some of the tallest and most famous buildings in the world, including the Sydney Opera House, the Petronas Towers in Kuala Lumpur, and Canary Wharf in London's Docklands.
