Charles is determined that his wife should be crowned queen one day

The Prince of Wales remains determined that Camilla will be crowned his queen by the time of his own coronation, it was reported last night.

The Prince of Wales remains determined that Camilla will be crowned his queen by the time of his own coronation, it was reported last night.

Prince Charles believes public opinion may shift in favour of his wife-to-be over the coming years. Senior courtiers are said to have pointed to the careful wording of the official statement announcing the match. While definitive on the subject of her title following her marriage, it is far less so on the question of how she will be styled on Charles' accession.

"It is intended that Mrs Parker Bowles should use the title Princess Consort," said the Palace communiqué in a formulation that leaves open a change in the future. A senior royal official is quoted as saying in The Sunday Telegraph: "Ultimately what Mrs Parker Bowles is called is a matter for the government and the prime minister of the day. We will have to consider what people feel at the time."

While ensuring that Camilla is not called queen would require a new Act of Parliament, nothing would be required to allow the convention to hold.

Meanwhile, Clarence House is reported to be preparing for an official tour of the United States by the prince this autumn. Such a visit would be first major engagement as man and wife. The precise scope of the extent of her official engagement remains under discussion at Buckingham Palace. The question of whether she will have her own private secretary, for example, has yet to be resolved.

How much she does is likely to become an important issue as the couple seek to win public support. Already some are claiming that she is reluctant to take on a full programme. One newspaper quoted a friend as saying that she would struggle with the workload. "Anybody coming into the royal family struggles to cope because the pace never lets up. What you do today was put into the diary six months ago. Camilla had to cope with a lot but she has never worked in her life."

With the couple still assessing the initial reaction to their match, there was irritation at reports that the Queen had to bounce her son into marriage within Clarence House. "They are getting married because they love each other and want to be together. It's as simple as that," said one courtier.

The first churlish shoots of public antagonism towards Camilla began to emerge yesterday as opinion polls showed 65 per cent of those questioned blamed her for the break-up of Charles's marriage to Diana, and only 38 per cent approved of her being given the title Her Royal Highness.

With just 54 commemorative mug-making days to go until the Great Occasion, the royal memorabilia industry is not exactly looking forward to a bonanza. The level of caution within the business can be gauged from the comment of Bob Houston, the editor of Royalty magazine. "In media terms," he said, "if the wedding to Diana was Manchester United, then this one is more like Rotherham."

Neither Royalty nor its rival, Majesty, has any plans for weeks of multi-page coverage. Majesty's editor, Ingrid Seward, said: "We can't come out for Camilla. I've personally had a lot of hate mail when I've written positively about Camilla."

Also adopting a policy of wait and see are Royal Doulton and Wedgwood. The Franklin Mint has no plans to produce a Duchess of Cornwall figurine, which is bad news for lawyers, if no one else. And a spokesman for Royal Mail said there were no firm plans for a commemorative stamp.

The only person genuinely exercised by the nuptials is a man known to ardent followers of the Stuart royal line as King Michael, the rightful monarch.

Michael, Prince of Albany, said: "One minute Charles is caught fiddling his taxes and the next he suddenly announces he is getting married. Coincidence? I don't think so."

Someone marginally less indifferent, Diana's brother, Earl Spencer, is to be invited to the wedding as a gesture of reconciliation, according to reports.
