The alliance between Britain and the US, resting on deep foundations of shared history and strategic interest, is not overly affected by the personal relationship between a prime minister and a president.
Sometimes individual affinity is consequential, as when Margaret Thatcher and Ronald Reagan were aligned over cold war doctrine, or when Tony Blair put Britain in lockstep with George W Bush for the march to war in Iraq. But there is no prospect of Rishi Sunak forming such a partnership – for good or ill – with Joe Biden at this week’s Washington summit.
