The family photograph of the G-7 summit gave Saturday for many jokes. British Prime Minister Boris Johnson suggested lightening clothing for photographers. With or without shirts? We have to show that we are tougher than Putin," he said, referring to propaganda images of the Russian president in which he poses bare-chested, "let's show our pecs!"

In response to the joke, Canada's Prime Minister Justin Trudeau followed up on the joke, proposing "a bare-chested horseback display." "Horse riding is a good option," settled the president of the European Commission, Ursula von der Leyen, who avoided commenting on the clothing issue.

This Sunday is the first of the three days of the G-7 summit held in Elmau, in the German Alps, a meeting that precedes the NATO summit scheduled for Wednesday and Thursday in Madrid.
