Meet the new Prince and Princess of Wales. As of today, William and Kate have officially inherited the titles of Prince and Princess of Wales, formerly held by King Charles III and the late Princess Diana. “As my heir, William now assumes the Scottish titles which have meant so much to me,” the King said in his first public address as sovereign. “With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations, helping to bring the marginal to the centre ground where vital help can be given.” At the link in bio, read how Kate plans on making the title her own.
