FILE - In this June 22, 1982, file photo, Britain's Prince Charles, Prince of Wales, and wife Princess Diana take home their newborn son Prince William, as they leave St. Mary's Hospital in London. The world watched as Prince William grew from a towheaded schoolboy to a dashing air-sea rescue pilot to a father of three. But as he turns 40 on Tuesday, June 21, 2022, William is making the biggest change yet: assuming an increasingly central role in the royal family as he prepares for his eventual accession to the throne.
