The Queen had to met Donald Trump alone after Prince Charles and Prince William reportedly refused to meet the US president.
During the planning of the visit, the Royals made it clear they did want to be involved in Trump’s trip to Windsor Castle, it has been reported.
Prince Philip, who retired from public engagements last year but still attends events that interest him, is also said to have been unwilling to meet the president.
A royal source told theSunday Times: ‘This business of Prince Charles and William not being there for the Trump visit was a snub.
‘They simply refused to attend. It is very very unusual for the Queen to be there on on her own. Usually she is accompanied by somebody.
‘Prince Charles has been substituting for Prince Philip recently.’
Mr Trump caused controversy as he turned up late to meet the Queen, walked in front of her during an inspection of troops and let slip that they talked about Brexit.
A Whitehall official who also helped plan the visit said: ‘The Queen will do her duty, but among the wider family, they were not as enthusiastic as they were when Obama came.’
When Barack and Michelle Obama visited the UK in 2016 they had lunch with the Queen and Prince Phillip at Windsor Castle and a private dinner with the Duke and Duchess of Cambridge and Prince Harry at Kensington Palace.
If Mr Trump’s visit had been an official state visit, he would have been expected to see more of the Royal family.
