For this reason, despite being able to, Camilla has never used the title of Princess of Wales and has styled herself as the Duchess of Cornwall after her husband’s Duchy estate.
This, however, has not stopped people from calling Camilla Princess of Wales.
In 2010, fury erupted as the former Commonwealth Games chief Suresh Kalmadi managed to confuse Diana with the Prince’s present wife, Camilla.
He told a room full of startled reporters at a press conference: “Yes, Princess Diana was there.”

As the horror of what he had just said dawned on him, the bumbling official hastily corrected himself adding: “Prince Charles and [Camilla] the Duchess of Cornwall…
“Now they have gone off and they appreciated all the efforts made here.”
Clarence House did not issue a comment.
It was not the only blunder made by Mr Kalmadi, whose conduct around the 2010 Commonwealth Games came under scrutiny, with the Central Vigilance Commission (India’s anti-corruption organisation) asking the Central Bureau of Investigation to probe certain aspects of the games’ organisation.

Prince Charles was pictured surrounded by empty chairs as he sat in the sparsely filled swimming complex, which had been specially renovated for the games.
There were similar problems with other arenas, with athletes forced to compete in front of dozens rather than thousands of spectators.
One diplomatic source said: “India fought hard to get the games here for the first time.
“It has been such a shambles, the Indians have voted with their feet and are keeping away.”

Camilla, Duchess of Cornwall
Controversy over Camilla‘s title re-emerged in March, when some reports claimed that Charles was considering pushing for his wife to become Queen Consort, as is traditional.
Clarence House immediately issued a rebuttal of this statement, saying: “The intention is for the Duchess to be known as Princess Consort when the Prince accedes to the throne.
“This was announced at the time of the marriage and there has been absolutely no change at all.”
Camilla’s supporters have argued that her growing importance within the family, as well as her increasing popularity – she was ranked 8th most popular royal in a YouGov poll last year – have meant that the public would be happy for her to become Queen Consort.
