Britain's royal family at Day 1 of Royal Ascot

Britain's Queen Elizabeth II, Dutch King Willem-Alexander, and Queen Maxima (left to right), attend Day 1 of the Royal Ascot horse races at Ascot, west of London, on Tuesday, June 18, 2019. The five-day meet is one of the highlights on the horse racing calendar. Horse racing has been held at the famous Berkshire course since 1711 and tradition is a hallmark of the meeting. Top hats and tails are compulsory on parts of the course, and a daily procession of horse-drawn carriages brings the Queen to the event. [Photo: Adrian DENNIS / AFP]
