London’s renowned National Portrait Gallery said last week that it was ending a controversial sponsorship deal with BP, the latest British cultural institution to turn its back on the energy giant. This, the AFP news agency reports, after BP has sponsored the museum’s prestigious Portrait Award since 1989. The Royal Shakespeare Company and the Scottish National Gallery have both also severed links with BP, while the National Theatre in London has ended its sponsorship deal with Shell, under pressure from artists and environmental activists. The British Museum meanwhile is also under fire over a sponsorship deal with BP for a recently opened exhibition about the prehistoric site at Stonehenge.
