“And I think there’s a truth to that.
“William is the future King of Britain and the Commonwealth and, like it or not, part of his job was to choose a consort who would do the job well.”
This month will mark the tenth wedding anniversary of the Royal couple, who now share three children.
Although happily married now, their relationship wasn’t perfect at first, as the couple briefly split up in 2007.
Royal expert, Katie Nicholls said: “It was William who instigated that split.
“Kate wanted a sense of commitment and at that point in time, William wasn’t able to give it to her.”
Mr Lacey added to this in his 2020 book, Battle of Brothers, saying that William dumped Kate over the phone.
The Cambridges have not yet announced how they plan to celebrate their ten-year wedding anniversary, but considering current lockdown restrictions, it is likely to be a scaled-back event.
