Shares in BP have plunged to a 13-year low.
Earlier, the company revealed it's spent more than £1.5bn (€1.8bn) so far cleaning up the oil spill in the Gulf of Mexico.
The company's battered stock fell around 6% on the markets this morning to just over 300 pence, less than half the value they had just before the Deepwater Horizon rig exploded in April.
