BP shares appear set for their worst one-day fall since 2010 after a judge ruled the oil company had been negligent in events leading up to the 2010 Gulf of Mexico oil spill.
The company's shares were down by 6% at the close of trading in London - making it the worst performer on the FTSE 100.
The ruling could add billions of dollars in fines to the more than £25 billion the company has already been charged for the disaster.
