Perhaps supporting the King during his treatment. Meeting with Oncologist? Normally the Queen would do that, but for her to pull out of the memorial service would have set alarm bells ringing regarding the Kings health. Perhaps easier for William to do it? Calendergirl, I was interested to read about the D of Windsors grave. Latterly, theirs was such a sad story you couldn't help but feel sorry for them. It's nice to know that the late Queen did visit the Duke when he was dying and that she allowed the burial at Frogmore which had for years been refused.
