A U.S. team probing the causes of last year's massive BP oil spill has delayed the release of its final report in order to more fully weigh the evidence, investigators said...The government's findings on the spill that killed 11 workers and ravaged the Gulf coast last summer has been widely anticipated by investors for clues on possible legal ramifications BP…and its partners may face from the disaster. The U.S. Coast Guard and Bureau of Ocean Energy Management was expected to release the results of their joint investigation next Wednesday, but the team said they need more time to "ensure that all evidence is properly weighed and considered."…More charges could be brought, however, and the report's findings could also affect lawsuits that BP and its contractors have filed blaming each other for the biggest offshore oil spill in U.S. history.
