BP has been given permission to restart deep drilling in the Gulf of Mexico, one year after the Deepwater Horizon explosion killed 11 workers and caused the worst oil spill in history. The group plants to drill 10 existing wells from this summer, following a deal with US regulators to continue work halted by a moratorium imposed after 200 million gallons of oil were leaked into the Gulf.
