President Donald Trump is to return to Buckingham Palace when the Queen hosts a reception for Nato leaders.
The Queen will welcome the world leaders and their partners for the reception next Tuesday which is part of events marking 70 years of the alliance.
But the Duke of York, who is facing a backlash following his BBC Newsnight interview about convicted sex offender Jeffrey Epstein, has not been named by Buckingham Palace as attending.
Many members of the monarchy will be present, with the Queen, the Prince of Wales and the Duchess of Cornwall formally greeting the politicians and their partners.
Other royals attending include the Duchess of Cambridge, the Earl of Wessex, the Princess Royal, the Duke and Duchess of Gloucester and Princess Alexandra. The Duke of Cambridge will be away on an official visit to the Middle East.
Andrew has stood down from all public duties after he was criticised for showing little sympathy with Epstein’s victims and no remorse for his friendship with the disgraced financier.
With all the Queen’s children attending the prestigious palace event bar Andrew, it is likely he would have attended if circumstances had been different.
During the reception the Queen and Charles will pose for a group photo with all the world leaders.
Mr Trump has repeatedly criticised the military alliance, describing it as “obsolete and disproportionately too expensive (and unfair) for the US”.
He received a ceremonial welcome and a banquet at Buckingham Palace during his state visit to the UK in June.
He later boasted about having “automatic chemistry” with the Queen, and praised her as a “spectacular woman”.
