BP has lost its bid to have its fine reduced over the 2010 oil spill in the Gulf of Mexico.

The oil giant appealed to have its maximum civil fine capped at $3,000 per barrel spilled under the US Clean Water Act.

But a US judge rejected the appeal and BP could be fined $4,300 per barrel, totalling $13.7bn (£8.9bn).

The court is yet to determine how much BP will be fined.

The 2010 oil spill at the Deepwater Horizon rig killed 11 people and caused the single largest oil spill in US history.

So far, BP said the oil spill has cost $42bn in cleanup costs, compensation for victims and fines.
