Britain's Kate, the Duchess of Cambridge, foreground, and Meghan, the Duchess of Sussex greet each other as they attend the Commonwealth Service with other members of the Royal family at Westminster Abbey in London, Monday, March 11, 2019. Commonwealth Day has a special significance this year, as 2019 marks the 70th anniversary of the modern Commonwealth - a global network of 53 countries and almost 2.4 billion people, a third of the world's population, of whom 60 percent are under 30 years old.
