One thing that Keir Starmer should not do, as he seeks to manage the relationship with the incoming president of the United States, is leak private details of his phone calls with him.
So it is unlikely that the prime minister was responsible for telling The Times that Donald Trump “veered off on a series of tangents” in their conversation on 18 December. The president-elect said that so many birds were being killed flying into wind turbines in the US that the coyotes were growing fat. If Starmer, or anyone acting on his behalf, did leak it, it could prove quite the misstep.
