Justin Trudeau puts big smiles on the Queen, Prince Harry and Prince Charles's faces at state banquet

We don't know what he was saying, but Prime Minister Justin Trudeau was clearly on his A game at a state banquet on Thursday (April 19), where he put huge smiles on the faces of the Queen, Prince Harry and Prince Charles. The charming Canadian leader is in London for the Commonwealth Heads of Government Meeting, during which he attended the black-tie affair at Buckingham Palace. The event was definitely the glitziest of the week, though the most celebrated new attendee of the CHOGM - Meghan Markle - was taking a night off from soon-to-be-royal duties.

Clad in the Girls of Great Britain and Ireland tiara along with a diamond-crusted necklace and dazzling earrings, the Queen was clearly charmed by the 46-year-old politician, breaking into a wide smile as he shook her white-gloved hand. "This dinner is always an opportunity for us to come together, as friends, and I am grateful that so many of you are here with us this time," she said as she addressed the crowd, revealing her happiness to be hosting this globe-trotting event as head of the Commonwealth back in her hometown.

Prince Charles was in stitches as he and Justin had a chat, the future monarch shutting his eyes to enjoy a hearty laugh. Charles looked dapper in a tuxedo, as did his sons Prince William and Prince Harry, who had been at a Women's Empowerment reception earlier in the day with fiancee Meghan (just one month to go until their royal wedding!). Harry and Justin, who spent some quality time during last year's Invictus Games in Toronto, had a chance to catch up, too - and both could be seen smiling during their chat.

The event also saw the likes of Princess Beatrice, the Countess of Wessex, the Duchess of Cornwall, Princess Anne and Prince Andrew. It is likely to be one of the Queen's last as head of the Commonwealth, and she revealed for the very first time today that she would be handing over the title to her son. “It is my sincere wish that the Commonwealth will continue to offer stability and continuity for future generations and will decide that one day the Prince of Wales should carry on the important work started by my father in 1949,” she said as she officially opened the event.
