In June 2012, The Foundation of Prince William and Prince Harry was renamed The Royal Foundation of The Duke and Duchess of Cambridge and Prince Harry, to reflect Catherine’s contribution to the charity. The Duke and Duchess were announced as ambassadors for the 2012 Summer Olympics in London, alongside Prince Harry. As part of her role, the Duchess attended numerous sporting events throughout the games. In September 2012, the Duke and Duchess embarked on a tour of Singapore, Malaysia, Tuvalu, and the Solomon Islands as part of the Queen’s Diamond Jubilee celebrations. During this overseas visit, she made her first official speech abroad, while visiting a hospice in Malaysia, drawing on her experience as patron of East Anglia’s Children’s Hospices.
After the birth of Prince George, the Duchess carried out her first engagement in late August when she accompanied the duke to meet runners preparing for an ultra-marathon on the isle of Anglesey, where they have a residence. At the beginning of March 2014, details were announced of the half-month-long tour to New Zealand and Australia that the couple and son would be taking from 16 to 25 April. The tour was Catherine’s first visit to the area and Prince George’s first major public appearance since his christening in October 2013. The tour began in New Zealand where they visited Wellington, Blenheim, Auckland, Dunedin, Queenstown and Christchurch. It ended in Australia where they visited Sydney, the Blue Mountains, Brisbane, Uluru, Adelaide, and Canberra.
On 21 July 2014, it was announced that the Duchess would be making her first solo trip, visiting the island of Malta on 20–21 September 2014, when the island was celebrating its 50th independence anniversary. Her trip was cancelled, with the Duke taking her place, after the announcement of her second pregnancy in early September. In April 2016, the Duchess and her husband undertook a tour to India and Bhutan.
In March 2011, the Duke and Duchess set up a gift fund held by The Foundation of Prince William and Prince Harry to allow well-wishers who want to give them a wedding gift to donate money to charities they care about instead. The gift fund supported 26 charities of the couple’s choice, incorporating the armed forces, children, the elderly, art, sport and conservation. These causes are close to their hearts and reflect the experiences, passions and values of their lives so far.
The Duchess has a number of patronages: The Art Room, National Portrait Gallery, East Anglia’s Children’s Hospice, and Action on Addiction, Place2Be, Natural History Museum, Anna Freud Centre, Sport said, and The 1851 Trust. The Duchess is joint Patron of 100 Women in Hedge Fund’s Philanthropic Initiatives, along with Prince William and Prince Harry. In 2017, she became patron of The Lawn Tennis Association, All England Lawn Tennis and Croquet Club and Action for Children.
