The British Museum is facing a flash mob-style protest on August 14. Unofficial guides will lead visitors through the collections and point out dodgy pasts behind them. Art experts and culture workers from Nigeria, Iran, Egypt, the Caribbean and Greece will reveal the connections between the legacy of the British Empire, the ongoing battle to return stolen artefacts to their places of origin and the museums continuing sponsorship by fossil fuel firm BP. Zita Holbourne is the joint national chair of Artists’ Union England and the national vice president of the PCS Union.”]
