EDINBURGH Festival performers joined a group of environmental campaigners yesterday to protest against the event’s most controversial sponsor, oil company BP.

The Theory of Everything actor Simon McBurney and writer Daniel Bye were joined by Alison Johnstone MSP in the re-enactment of BP’s Gulf of Mexico spill outside Usher Hall.

The protest piece, named Gross Negligence, was directed by performance activism group BP or not BP? with the help of Friends of the Earth Scotland and Edinburgh University People & Planet.
