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

The Duchess was admitted to St Mary's Hospital in London in the early stages of labour on the morning of 22 July 2013 and gave birth
