First, Kate will have more thank-you letters to write after the wedding than most of us accumulate in a lifetime; and given that these will be kept for ever by their recipients, they can’t be dashed off. Or typed.

She is also said to be polishing her French for their tour of Canada, which begins on June 30. She is very much aware that the nation’s sizeable French-speaking population will judge her on her accent and command of the language — the Queen, Prince Charles and Prince William are all fluent.

To cap it all, she must plan that influential wardrobe, to encompass conservative Canada and the tour’s second leg, taking in laid-back California and in particular glitzy Los Angeles.

Wardrobe worries are best tackled in London, where she can try on the clothes that arrive at her London residence Clarence House (some are sent on spec, others called in).

She drives herself back from Anglesey in her Audi, or travels in a Range Rover with her protection officers, and in the capital her mother and sister Pippa — and Private Secretary to the Princes, Helen Asprey — are happy to be fashion advisers.
