Royal Households of the United Kingdom Queen and the Prince of Wales, had approved a plan that would have the Duke and Duchess of Cambridge permanently move to a larger apartment in Kensington Palace in 2013, after it is renovated. This apartment was previously occupied by the Queen's sister, Princess Margaret, Countess of Snowdon and her husband Antony Armstrong-Jones, Earl of Snowdon after their marriage in 1960. The apartment was retained by Princess Margaret after her divorce in 1978 and was her London residence until her death in 2002. Prince Harry will then move his official residence from Clarence House to the apartment vacated by the
Diana Wellesley, Duchess of Wellington Stratfield Saye. In 1972 Lord Douro's father died and he and his wife became Duke and Duchess of Wellington. At home the Duchess tended personally to the gardens and was amused to be mistaken frequently for a gardener when their home was open to the public. The Duchess died at the family home, Apsley House, in London on 1 November 2010, aged 88. She lived to see the births of several of her great-grandchildren, including twins Lady Mae and Arthur, Viscount Wellesley, third in the direct line of succession to the dukedom. Diana McConnel became Marchioness of Douro upon marriage
