Obviously, such a report fuels speculations of an impending engagement between Prince William and Kate. Also from the said aide is the news that Prince William and Kate have been invited to spend their Bank Holiday in August at the main castle at Balmoral. During previous visits, the pair stayed at lodgings on the estate but not at the castle itself.
If Kate will indeed have lunch alone with the Queen, there can only be topic of serious discussion, and that is the change in Kate’s life upon marrying a future king.
As always, it is hard to know the accuracy of reports like this. We’ll just have to wait and see what happens, as we’ve always done.
