Britain is in talks with European allies about releasing emergency diesel stockpiles after Donald Trump threatened to cut off US fuel supplies.

Ministers held calls with counterparts from the European Commission, Germany, France, Italy and Ireland on Thursday to discuss whether to draw down reserves. The Trump administration told Germany and France to release their stockpiles to help ease soaring global energy prices, warning of a US export ban if they refused.

The talks suggest Britain is considering whether to join other European nations in releasing strategic reserves in response to Trump's pressure and the global energy situation.
