Yesterday, we saw that Her Royal Majesty received many kind letters congratulating her on this achievement, and she spent the eve of her Accession Day with members of the Sandringham Women’s Institute, pensioners who live on the Sandringham Estate, West Norfolk Befriending and Little Discoverers, an early-years charity for children with disabilities.
But today, someone very close to the queen sent her a letter of congratulations for her incredible achievement. Queen Elizabeth's eldest son (and the heir apparent), Prince Charles, wrote a personal message that he shared to Instagram. A snapshot of the letter was posted to the Clarence House account, with a caption that said, “A message from The Prince of Wales on the 70th anniversary of Her Majesty The Queen’s Accession. #PlatinumJubilee #HM70.”
