Prince William and Kate Middleton, who are on a nine-day tour of Southeast Asia and the South Pacific on behalf of the Queen to commemorate her diamond Jubilee, have rounded off their first leg of the tour.

The Duke and Duchess of Cambridge ended their Singapore visit by spending some time at the Kranji Commonwealth War Cemetery, located in the Kranji suburb of northwestern Singapore.

According to the Commonwealth War Graves Commission (CWGC), 4,461 Commonwealth casualties of the Second World War are buried or commemorated at the Kranji War Cemetery, although 850 of the burials are unidentified. In addition to World War II graves, the cemetery has 64 First World War burials and commemorations.

William and Kate together laid a wreath of red roses and white orchids at the Singapore Memorial, which stands within the cemetery and bears the names of over 24,000 casualties of the Commonwealth land and air forces who have no known grave.

Kate, wearing a Jenny Packham pleated duck egg blue dress with a laced bodice, curtseyed to the memorial after laying the wreath. The royal couple moved across the cemetery deep in thought as well as chatting along their way through the rows of graves, before flying off to Malaysia for the second leg of their Far-East tour.

William and Kate were on a three-day tour of Singapore, where they took part in several events held in their honour. On the first day, they visited the National Orchid Garden in the Singapore Botanic Gardens, where an orchid hybrid was named in their honour - the Vanda William Catherine. On the second day, the royal couple visited Gardens by the Bay, a school for disabled children and the Singapore factory of Rolls-Royce.

After spending the second day touring the city-state, Prince William and Catherine, the Duchess of Cambridge, attended a British Gala reception at the Eden Hall in Singapore, where they made a toast in the honour of Her Majesty, the Queen's Diamond Jubilee.
