U.S. President Donald Trump has publicly urged U.K. Prime Minister Keir Starmer to lower taxes, curb immigration and crack down on crime, arguing that adopting a tougher stance on these issues is essential if Starmer wants to defeat Nigel Farage’s populist Reform UK party at the next general election. Trump delivered the advice during a visit to Scotland on 28 July and expanded on his criticism the following day in a series of posts on Truth Social. He described North Sea oil as a “treasure chest” for Britain but said current tax levels are so high that investment “makes no sense,” calling on the government to “incentivize the drillers, FAST.”
