Prince Harry and Meghan, the Duke and Duchess of Sussex, have christened their daughter Princess Lilibet Diana in California, with the Archbishop of Los Angeles officiating. The title of princess was granted to Lilibet under the 1917 rules set out by King George V, and her parents invited the British royals to the event, though they did not attend. The christening marks a significant milestone for the Sussexes, as they continue to raise their daughter in the US.
