Princess Anne has been caught on camera shrugging at the Queen as the monarch spoke to Donald Trump at Buckingham Palace .

The royals had a brief exchange as the Queen greeted the US president at a Nato reception on Tuesday.

Footage circulated on social media showed the monarch, stood alongside Prince Charles, turning towards her daughter as she stood a few feet away from the royal receiving line.

The Princess Royal then shrugs and says, “It’s just me”, to signal there are no more dignitaries for her mother to greet – prompting laughter from Mr Trump. Gesturing behind her to members of the royal household, she adds: “And this lot”.
