As far as the royal family is concerned, however, she will be Duchess of Cornwall — a concession to public opposition to the new wife assuming any of the titles of the late Princess Diana.
When the wedding was announced in February, Charles' office said that when he becomes king, "it is intended" that she will be Princess Consort (search).
That's clearly a bow to opinion polls which show some 70 percent of the population opposed to her being queen, Princess Consort is a novelty for a monarch's wife, although Prince Consort is a traditional title for the husbands of monarchs.
In both cases, the consorts have no power.
Charles' office believes Parker Bowles can take a title of her choosing from a grab bag of her husband's offices: Prince of Wales, Earl of Chester, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles and Great Steward of Scotland, and Duke of Cornwall.
Indeed, when in Scotland she will be styled Duchess of Rothesay.
The government, however, has said that if Charles becomes king, she will be the queen unless the law is changed.
