The multibillion-dollar trial of BP over its part in the worst oil spill ever in the US...has been postponed. BP is accused of ultimate responsibility for the 2010 Deepwater Horizon rig disaster, when an explosion in a well led to the deaths of 11 workers and hundreds of millions of gallons of oil leaking across the Gulf of Mexico. The case, which could last two years, will begin on March 5...BP and the Plaintiffs' Steering Committee confirmed that the US District Court in New Orleans had adjourned the start of the trial by a week to allow them to continue discussing a possible settlement agreement...Whether BP settles or not, the case is virtually guaranteed to prove the most expensive environmental disaster in history, far surpassing the Exxon Valdez spill off the coast of Alaska...[also refers to Transocean, Halliburton]
