NATO leaders appear to gossip about Trump in unguarded chat

While NATO leaders are professing unity as they gather for a summit near London, several seem to have been caught in an unguarded exchange on camera apparently gossiping about US President Donald Trump's behaviour.

In footage recorded during a reception in London at Buckingham Palace Tuesday evening, Canadian Prime Minister Justin Trudeau was seen standing in a huddle with French President Emmanuel Macron, British Prime Minister Boris Johnson, Dutch Prime Minister Mark Rutte and Britain's Princess Anne, daughter of Queen Elizabeth II.

After Johnson asked Macron, "is that why you were late?" Trudeau could be heard saying "he was late because he takes a 40-minute press conference off the top".

That appeared to be a reference to Trump's long and unscheduled question-and-answer session with journalists earlier Tuesday.

Trudeau also said: "You just watched his team's jaws drop to the floor."
