Activists have managed to shut off BP petrol stations in London in a bid to encourage the oil giant to go green.
On Tuesday supplies of petrol were reportedly shut off at around 50 stations in central London by Greenpeace protesters.
The fuel supply was stopped after activists flipped safety switches on the forecourts and then removed them to stop employees reopening the BP stations.
The Greenpeace activists then hung signs at the affected stations saying: "Closed. Moving beyond petroleum".
Thebreakdown in relations between the parties has come as BP is expected to announce a replacement for outgoing chief executive Tony Hayward.
The protest is a bid to urge Bob Dudley who is expected to take the helm from Mr Hayward to move away from "his predecessor's obsession with high risk, environmentally reckless sources of oil".
Greenpeace executive director John Sauven said: "We've shut down all of BP's stations in London to give the new boss a chance to come up with a better plan. They're desperate for us to believe they're going 'beyond petroleum'. Well now's the time to prove it."
A BP spokesman said activists had only managed to close down around a dozen service stations, adding that they would be reopened as soon as it was safe to do so.
