There is nothing in law to stop Camilla Parker Bowles from calling herself the Princess of Wales after her marriage to Prince Charles on Friday.

By law, she would be entitled to adopt any of her husband's long list of titles, and an Act of Parliament would be needed to prevent her, the Constitutional Affairs Minister Christopher Leslie will tell MPs.

The Prince's advisers have said that she will be known as the Princess Consort.

They have also said that she will not be called the Princess of Wales, to avoid offending friends and admirers of the late Princess Diana.

"She will be the Princess of Wales, but she will not be using the title," a spokeswoman for the Constitutional Affairs department said.
