The stick was the same as the one the Queen was seen using in 2004 after an operation to remove torn cartilage from her right knee. It appeared noticeably more battered, raising the possibility that it has been used in private since then.
It was not identified as being from one of the Queen’s official Royal Warrant holders, where more ornamental walking aids sell for up to £5,995 for a wooden pole topped with a diamond, pearl and rose gold falcon.
The monarch did not appear to lean on the cane during the engagement, moving easily to her seat and to greet members of the congregation.
It is not the first time she has made small concessions to the practicalities of working in her 90s. In 2016, she used a lift to enter Parliament for the State Opening, avoiding the 26 steps of the Royal Staircase at the Sovereign’s Entrance.
She has also not worn the heavy Imperial State Crown since 2016, instead having it placed on a deep red and gold velvet cushion during the proceedings.
The monarch joined an Abbey congregation of serving members of the military, veterans, their families and General Sir Nick Carter, the Chief of the Defence Staff.
