WASHINGTON, United States (AFP)—United States (US) President Donald Trump criticised outgoing British Prime Minister Keir Starmer on Monday after the Labour leader announced he would resign, saying he had “really hurt himself” over energy, immigration and his handling of relations with Washington.

“I think he’s a lovely man,” Trump told reporters at an Oval Office event, before accusing Starmer of mishandling Britain’s energy policy by failing to exploit North Sea oil and allowing “windmills all over the place.”

“The UK buys much of its energy. You know where? Norway. You know where they get their oil? The North Sea,” Trump said. “The UK has a much better portion of the North Sea — they don’t want to do it for environmental purposes.”
