Prince Charles got an unofficial vote of support from his subjects on Wednesday, when a poll revealed that 43% of Britons said that he should go ahead and marry his longtime companion, Camilla Parker Bowles, compared to 32% who said that the couple should not marry. Another 26% admitted that they just didn't know. The survey, conducted by a firm called ICM for the Guardian newspaper, follows fevered speculation over whether or not the prince's mother, Queen Elizabeth II, plans to allow the marriage. Royal heirs need the monarch's approval to wed, but religious and constitutional questions and fears of offending the memory of his late ex-wife, Princess Diana, complicate Charles's situation. In August 1998, a year after Diana's death, 46% of Britons said they opposed a second marriage for Charles, and only 35% approved. The current poll consisted of 1,004 respondents and was conducted by telephone between Friday and Sunday, and is said to have a margin of error of three percentage points.
