It was announced on 8 September that the Queen had died following a short illness, attended by all four of her children. She was Britain’s longest reigning sovereign and the world’s oldest monarch. On 6 September she had presided over the ceremonial handover of power to new prime minister Liz Truss at Balmoral, her summer residence. Her oldest son, now King Charles III, said his mother's death was a moment of ‘the greatest sadness for me and all members of my family’. Justin Welby said, ‘As we grieve together, we know that, in losing our beloved Queen, we have lost the person whose steadfast loyalty, service, and humility has helped us make sense of who we are.’
