Do you have credible sources to back up the part that's been bolded or is that supposition? I've yet to see something come out that tells exactly what the Queen is or isn't doing in regards to Andrew's situation.
I have read it in what I thought were reasonable sources, which I don't have time just at this moment to look up but would be happy to dig up and submit. If what I wrote doesn't pass muster I'm happy to edit it out or have it deleted, I'm new here and if I did not read the rules carefully enough that's my own fault. I certainly don't want to ruffle feathers with my first post.
It is supposition in that I assume only the Queen has the power/desire to warn the press off Balmoral at this delicate time - I understand that's most unusual - and that the reason is to protect Andrew, since no one else at the place has any reason to worry about anything more than the usual press attentions.
