A royal consort is the spouse of a ruling king or queen. Consorts of monarchs in the United Kingdom and its predecessors have no constitutional status or power but many have had significant influence. Prince Philip is the longest-serving and oldest-ever consort. His mother-in-law, Queen Elizabeth The Queen Mother, who died aged 101, lived longer than any other royal consort but at the time of her death she did not hold the position of queen consort, as her husband King George VI died 50 years before her. Since the death of Prince Philip, the position is vacant. Camilla, Duchess of Cornwall, is expected to become the next royal consort upon the accession of Charles, Prince of Wales, as king.
