Diplomats have advised the UK prime minister to have a face-saving response just in case he comes low down on the list at the inauguration

Donald Trump may invite ­populist rightwing leaders from Europe such as Italy’s Giorgia Meloni and Hungarian prime minister Viktor Orbán to the White House before Keir Starmer, senior UK ­diplomats believe.

Downing Street and the Foreign Office are eagerly pressing for the prime minister to be at the head of the traditional “beauty parade” of overseas leaders who are called to see the new president in the days after the inauguration on 20 January. Representations are being made via the UK embassy in Washington.
