'Of course it could happen again': experts say little has changed since Deepwater Horizon

The danger of deepwater oil operations, combined with the loosening of Obama-era rules, mean the risk of a repeat disaster is high

A massive deepwater oil spill is nearly as likely today as it was in 2010, experts warn, 10 years after the disastrous explosion of BP's rig in the Gulf of Mexico that caused an environmental catastrophe.

The blowout killed 11 workers and spewed 4m barrels of petroleum into the ocean for 87 days before it could be capped, devastating marine life and polluting 1,300 miles of shoreline. Thousands were put out of work in oil, fisheries and tourism.
