“When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me,” she said in a statement released by Buckingham Palace, “and it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service.”
According to The Guardian, a queen consort is defined as the wife of a reigning king. After Camilla and Charles were married in 2005, the palace declared she would be known as HRH The Duchess of Cornwall—rather than the Princess of Wales, a title used by his ex-wife, the late Princess Diana.
The Queen’s late husband, Prince Philip, served as the consort of the British monarch from Elizabeth’s accession in 1952 until his death in April 2021, making him the longest-serving royal consort in history.
