The late Queen's old friend told The Daily Beast, "For the last years of her life, certainly from when her husband died [in April 2021], the queen was in a lot of pain."
"In the final months, of course, it got very much worse; by the time of the Platinum Jubilee (June 2022), she couldn't see very much, she couldn't hear very much, and she was easily confused," they continued. "She barely moved from her apartments in Windsor Castle. Appearing on the balcony at the jubilee required a titanic effort."
