I think it's true to say the staff will have prepared a plan for how they would deal with it in general but not specifics eg wedding venue.
The staff have always said they expect to be given 3 days notice to prepare for an announcement.
My guess is still they will wed next summer but I honestly believe they haven't discussed it with any of their staff or wider family+friends
...a friend of his tells me William doesn't even know if he'll be at Sandringham at Christmas or New Year. He may be on duty at RAF Valley.
As for the suggestion that William will go to Sandringham at Christmas to ask the Queen for permission to marry Kate....
But I am told that it's very unlikely at this stage that the Middletons would get an invite to the Big House.
I wondered if the shooting lessons might be a precursor to the Queen inviting the Middletons to Sandringham after Christmas.
Against that, I am told that the Middletons have never met the Queen and the likelihood of them meeting in the near future is remote.
To bring the Queen into the equation by involving her estate officials and the Royal Family's lawyers seems to me to advance the wedding.
What does all this mean for a royal wedding? Your guess is as good as mine. William is very protective of Kate and her family.
The argument for harassment is that the royal party claim they asked the photographer to move on several times. Was he just doing his job?
Clearly, we in the media will seize on these pics as evidence that a royal wedding is moving closer, something our readers want to read.
I'm told the pics of the Middletons were taken from a public road, looking onto Balmoral land open to the public.
I imagine lawyers for the media would argue there was genuine public interest in Michael and Carole Middleton being photographed at Birkhall
I am told a group of kids doing the Duke of Edinburgh Award scheme were on the same bit of land 15 minutes later.
William and his advisers are examining the possibility of legal action, claiming the royal shooting party was harassed.
The Queen's Balmoral estate is consulting lawyers about pictures that appeared today of the Middletons on a shooting trip at Birkhall.
Not much to show for me in tomorrow's newspaper so I'm going to tweet a few things I have learned about the Royal Family and the Middletons
