I posted some while back re the Patriots Flag. Amongst those to whom I wrote was Duke of Edinburgh. He has now responded that contact with Dean of Westminster confirms the Flag was moved from it's position alongside the Tomb of The Unknown Warrior because it was being damaged by air currents and UV rays from the sun. The new location gives protection from these dangers. Understandable. Hopefully, contact at his level has put the Dean on notice that the importance of maintaining our links with the past cannot be treated lightly.
