Hugo Vickers predicted the prince and his former flatmate could prove to be an alternative focus for young people. The writer described how it would be Miss Middleton’s “duty” to produce an heir and keep her husband happy.
“Obviously the first thing that happens is that Prince William is like a figure on a chess board — a king creates a queen,” Mr Vickers said.
“It makes it possible to have another generation of the House of Windsor in direct line to the throne — a boy who will automatically become king or a girl who might be queen. If I’m being brutal about it, Catherine’s duty is to make her husband happy and to produce an heir. What she brings to it — she will be the first queen who has a university degree.”
The author spoke of how the couple could eclipse celebrities such as David and Victoria Beckham — who will be guests at the wedding — as a focal point for a generation.
“I think there’s a very good opportunity for William and Catherine to replace people like the Beckhams for the focus of young Britain,” he said.
He added: “I think it will be wonderful that during the Queen’s reign you may get another prospective generation — our 85-year-old Queen with Charles, William and a little boy or girl. Continuity is so important.”
Mr Vickers said the royals would be thrilled at Kate’s approach so far.
“She’s an intelligent girl. She has a good head on her shoulders and is so much older than Diana was and she knows William,” he said.
“Diana called Prince Charles ‘Sir’ right up to when they were engaged.”
He added: “(The Royal Family) must be delighted. She’s cautious. She’s very measured — confidence is not quite the right word, but she is assured.”
Mr Vickers said: “What I like about this wedding is that it’s been entered into calmly, soberly and with enormous discretion.”
He predicted that William would put on his own stamp as monarch.
“We don’t know, and I don’t suppose they will know, what kind of king and queen they will make,” he said.
“In guidance, if you look at the way William fulfils his duties at the moment, such as in Christchurch, New Zealand, it seems to be a mixture of the traditional and the informal.
“It will be a gradual process. He will put on his own stamp.”
