It would seem not even world leaders are averse to a bit of playground-style gossip about their colleagues.
The ongoing NATO summit in London has been notable for a few frosty meetings between the prime ministers and presidents who have gathered, notably between Donald Trump and French counterpart Emmanuel Macron.
Now Mr Macron, who riled Mr Trump by describing NATO as suffering from strategic brain death, appears to have been caught on camera gossiping about an unnamed associate with Canadian Prime Minister Justin Trudeau.
During footage from a reception at Buckingham Palace, the pair are seen chatting with Boris Johnson and the Dutch prime minister Mark Rutte and can be heard joking about a 40 minute press conference that had run late.
When Mr Johnson asks Mr Macron is that why you were late?, Mr Trudeau replies he’s late because he takes a 40 minute press conference off the top – seemingly a reference to the Macron-Trump meeting earlier in the day.
Princess Anne is also seen on the fringes of the conversation, which appeared to show Mr Trudeau making another cheeky remark about the press conference.
He tells his fellow leaders: You just watched his team’s jaws drop to the floor.
Mr Trump certainly made his presence felt in London during several media briefings on Tuesday, not just in his tense appearance alongside Mr Macron
The US president used a press conference with NATO Secretary-General Jens Stoltenberg to say he would not be offering any comment on the UK general election – only to then immediately do just that.
Mr Trump said: I’ll stay out of the election. I’m a fan of Brexit, I called it. I was here, they asked if it was going to happen and I said yes and they smiled, it was just my opinion.
I’ll stay out of it, but Boris is very capable and I think he will do a good job.
Mr Trump and his fellow leaders capped off the day by marking the 70th anniversary of NATO at Buckingham Palace, where they posed for a traditional group photo alongside the Queen.
On Wednesday, Mr Johnson will address leaders from all 29 member states at The Grove hotel in Hertfordshire.
The prime minister will attempt to bring harmony to the top of the alliance by echoing a famous phrase from the classic French adventure story The Three Musketeers, reminding colleagues that it is one for all, and all for one in the quest to keep their people safe.
The meeting is expected to consider new threats, including in the areas of cyber and space, after NATO last month declared space one of its operational domains alongside air, land, sea and cyber.
