Queen or queen consort? What to know about Camilla's title

The question of what title Camilla would hold when Charles became king has long been a subject of contention, due to sensitivity about her status as Charles' second wife.

Camilla and her first husband, Andrew Parker-Bowles, divorced in 1995, shortly after Charles gave an explosive television interview admitting his relationship with Camilla. Charles and Diana divorced the following year. In 1997, there was a global outpouring of grief when Diana died in a car crash. Camilla and Charles waited until 2005 to marry in a low-key private civil ceremony.

Queen Elizabeth II settled the matter last year, when she gave the blessing for Camilla to be known as queen consort. The endorsement was widely seen as a formal sign that the royal family had finally accepted Camilla as a respected senior member.

Last month, Buckingham Palace's official coronation invitations referred to Camilla as "Queen Camilla" for the first time. At the time, British media reported that palace officials believed it was an appropriate time to introduce the title, because several months had lapsed since Elizabeth's death in September.

The most recent queen consort in British history was George VI's wife, Queen Elizabeth, who was known as "The Queen" and later the Queen Mother.
