years later Tony Blair's press secretary Alastair Campbell noted that at a dinner at 10 Downing Street in 2002 to mark the Queen's Golden Jubilee, attended by five prime ministers and several relatives of deceased prime ministers: In 1994, 17 years after her husband's death, Lady Avon unveiled a bust of Eden at the Foreign Office. In 2013 she attended a memorial service for Sir Guy Millard (1917–2013), one of Eden's long-serving private secretaries and probably his last surviving close associate, having been with him and Churchill at wartime meetings with Roosevelt and Stalin and in Downing Street during the Suez Crisis. Longevity Lady Avon was the youngest wife of an incumbent prime minister in the twentieth century. She was only 36 when her husband resigned, and was widowed at 56. She outlived five later prime ministerial spouses and witnessed the administrations of 13 subsequent prime ministers. By contrast, Lady Dorothy Macmillan was 57 when her husband succeeded Eden and 63 when he resigned, dying just three years later; her husband outlived her by 20 years. As such Avon enjoyed unusual longevity for a prime ministerial spouse, contributing, for example, to a television documentary by Cherie Blair in 2005 about prime ministers' wives and to a three-part series the following year marking the 50th anniversary of Suez. In the latter, she recalled, among other things, Eden's disillusion with the lack of American support for British policy in 1956. The critic A. A. Gill was among those who praised Avon's erudite performance in the Blair documentary (""), while sensing that she appeared not entirely to approve of Cherie Blair. Avon was 87 when her memoir appeared in 2007. A journalist who interviewed her and her editor, Cate Haste, observed that Avon "seems slight and wan, as if painted in watercolour rather than oil", but described her as "vigorous and knowing" in conversation. In April 2008 she and Haste appeared at the Sunday Times Oxford Literary Festival, the literature for this event observing that, although Avon was perhaps best known for her lament about "the Suez Canal flowing through [her] drawing room", "she was far more than a drawing-room consort". Avon died on 15 November 2021 at her home in London, at the age of 101. She was the second longest-lived prime ministerial spouse after Lady Wilson of Rievaulx, widow of Harold Wilson, who died in 2018 aged 102. Her funeral took
