As the Duchess of Cornwall celebrates her 70th birthday with a party this weekend, a poll has revealed more people are warming to the idea that she should become Queen.
But the survey, for the Mirror newspaper, finds more people are opposed to it than support it.
When the couple married in 2005 only 7% surveyed said that Camilla should become Queen when her husband accedes to the throne.
Today that figure stands at 39%.
But the Mirror poll of 2,000 people found that 40% still do not want her to be called Queen.
The Duchess of Cornwall turns 70 on Monday - 18 months before Prince Charles becomes a septuagenarian himself.
The couple are hosting a private party at their Highgrove home today.
Camilla has struggled with her popularity ever since Princess Diana revealed Charles' affair with her.
The 20th anniversary of Princess Diana's death is coming up at the end of August.
The Mirror survey found 61% would prefer Diana to be Queen.
