The UK is not facing a diesel shortage despite fears that the US could restrict exports, transport minister Keir Mather said on Friday. He said Britain receives diesel from several sources and is discussing a possible release of emergency stocks with European countries.

The warning follows a threat from Donald Trump’s administration to cut US supplies unless Germany and France release reserves to help curb rising prices. About 30% of UK diesel comes from the US, while most of the rest comes from mainland Europe. Britain holds 42 days of reserve supplies.

Prices are already climbing. The RAC said the average UK diesel price reached a record 200.01p a litre on Friday, crossing £2 for the first time. The government has extended its 5p fuel-duty cut until the end of the year; the chancellor is expected to address its future at the budget, Mather said.
