Activists plan oil protest at British Museum

Art Not Oil coalition to use stunts and flashmob to shine spotlight on 10m BP sponsorship deal with arts organisations

Campaigners against oil firms sponsoring UK arts groups are to stage an all-day protest festival at the British Museum in what they claim will be their most ambitious intervention to date.

More than a dozen campaign groups are expected to converge on the museum on 13 September for "stunts, performances and creative interventions".
