It was reported tonight that King Charles has bought her a house that is closer to her family:

The house will revert to the Crown when she passes away
I would have thought that both Anne and Edward would have been there, as it was a tribute to the Queen, but then that would have raised the "Andrew" question. Can't have all the Queen's children there, except for one.
