When Queen Elizabeth passes on, Prince Charles will become the reigning King of England. But what does this mean for his wife, Camilla, the Duchess of Cornwall?
Technically, Camilla's role will transition into that of a queen, but it's unlikely that she will be referred to as the Queen of England.
When she got married to Prince Charles in 2005, she automatically received the HRH and Duchess status. In addition, she's legally the Princess of Wales.
However, in consideration of the former holder of the title of Princess of Wales, Princess Diana, Camilla does not use this term formally.
Even though Diana was legally no longer the Princess of Wales after she and Charles got divorced, the title had become so strongly associated with her that Camilla's decision to go without it made sense.
When Prince Charles becomes King, it's likely that he will be referred to as King George VII, which is his monarch name. Usually, when this happens, the wife of the king becomes a queen.
However, this may not be the case this time around. When Charles and Camilla got married, a statement was reportedly released by the Clarence House which said that Camilla will be known as 'Princess consort' when her husband takes the throne.
Apparently, it's a way of continuing with the status quo, as Prince Philip is officially the prince consort to the reigning monarch.
But bear in mind that when Charles becomes king, he will have the power to make any changes he wants and there is a pretty good chance one of them will include making his wife his queen.
So, really, we cannot say for sure until the time comes.
Prince Charles also reportedly plans to shake up the monarchy. Hence, his wife's title may not be the biggest surprise he has in store.
At the end of the day, only time will tell what it is to happen to official titles and plans for the British monarchy.
