So how might Britain be sucking up to Trump? A Labour MP, Ben Bradshaw, thinks that the government has not always done all it can to assist the Mueller inquiry into whether Trump’s campaign colluded with Russia. Bradshaw was the minister in charge of the Secret Intelligence Service, known as MI6, and has doggedly pursued allegations about Russian meddling in other people’s elections. ‘I’m told that Mueller’s team were over here late last year and they weren’t happy with the level of cooperation they were getting,’ he said. Another source, with links to the ‘intelligence community’, said this was continuing, even after the Skripal poisoning.

These claims — of a decision to go slow with Mueller, driven by expediency — have not been confirmed, but if true, the government may have miscalculated. Britain is trying to get a free-trade deal with the US as we leave the EU. And Theresa May was the first world leader through the door of the Oval Office to see the new president. But whatever promises she wrung from Trump will depend on a follow–through and focus he has not shown. This is a president who could not get his own healthcare bill past a Republican Congress.
