What can Keir Starmer say at the White House that Donald Trump might listen to? | Andrew Rawnsley

One of our senior diplomats once offered me an explanation of the allure: The red carpet is laid out, the national anthems are played, all that stuff is very seductive." This will be customarily accompanied by ritualistic words about the importance and invincibility of the special relationship".

Number 10 lobbied hard to get Sir Keir Starmer across the Atlantic early in the second term of Donald Trump and, until recently, Downing Street people were telling themselves that an encounter between the two men needn't be a disaster and might even turn out to be a success. In the weeks since Trump's re-election as US president, UK policy might be summarised by the phrase Don't poke the beast". Keep the temperature cool. Ignore provocations. Attempt to trade on British heritage - golf, the royal family - with which this US president has an affinity. Put David Lammy out there to suggest that there is lots to respect about the man whom the foreign secretary used to call a woman-hating, neo-Nazi-sympathising sociopath". Softly-softly was the doctrine and they thought it was bearing fruit.
