Trump told Europe to release diesel reserves or lose US supply.

Diesel in Britain hit a record just under 200p a litre this week, the RAC said.

The US exports 1.2 to 1.5 million barrels of diesel a day, and Washington reportedly wants Europe to release 120 million barrels.

A source familiar with the talks said reserves remain from an earlier coordinated release this year.

Britain and EU partners are discussing releasing more strategic reserves, including diesel, if needed.
