Downing Street is reported to be preparing for a Donald Trump victory next week.
If he does become leader of the free world, he would also be in line to meet the Queen and her husband, the Duke of Edinburgh – something he is not known to have done before except possibly in waxwork form at Madame Tussauds.
But will Her Majesty want to meet Trump?
By convention, the 90-year-old monarch always meets the US president. Starting with Harry S. Truman shortly after she ascended the throne in 1952 and going up to President Obama, she has met all 12 US leaders who have been in office during her reign with the exception of Lyndon B. Johnson.
Hillary Clinton is well ahead of Trump in the Royal stakes having met HM and Prince Philip on several occasions – both as First Lady and as Secretary of State.
Here is one recent occasion when they shook hands:
Mrs Clinton also attended the 1997 funeral in London of Diana, Princess of Wales, representing her husband, who was president at the time.
But what happens if Trump is granted an audience with the British monarch?
Court sources say the Queen has not been impressed by his adventures in her beloved Scotland, where the development of his golf course business has caused misery for some.
Trump bought the Menie estate, which lies on the east coast of Scotland in an area of great natural beauty overlooking the North Sea, for £7 million ($10 million) in 2006. His self-declared goal, unsurprisingly, was to create “the greatest golf course in the world”.
Even though some of the estate had been designated a site of special scientific interest (SSSI) because of its unusually shifting sand dunes, the bulldozers eventually moved in to create the 18-hole course anyway.
There is a strong suspicion that it could be a long time before HM finds space in her diary to see the would-be President Trump and his wife, Melania.
Scotland is her favourite place in the world.
