We often stay on the Sandringham estate Caravan club site, and my husband likes to roam the forest tracks early morning looking for wildlife, he has often passed a brief greeting with one of the Royals who were out walking their dog at the same time. We have also seen the Queen paying a private visit to the church one afternoon, closely followed by her lady in waiting and suited and wired man in a dark suit, probably her protection officer. At this time of year various Royals can be seen driving around the estate, often in Range Rovers, but sometimes in a rather old Defender, driven by a lady wearing a headscarf!
My Step brother is a retired Army officer, also with close connections to the Horse Racing world, and he’s met most of them at some point in his career, but is a personal friend of Princess Anne, who sends him a Christmas card every year.
