A moment of reflection as William and Kate honour war heroes

The Duke and Duchess of Cambridge's visit to Singapore has a poignant end, as they pay their respects at the Kranji War Memorial.

With their heads bowed, the couple were visibly moved as they laid a wreath for 24,000 commonwealth soldiers who fell during  World War II.

Sheltered from the tropical heat with a parasol, Kate looked lost in thought as she and William visited tombs on the hill-top site.

As a member of the armed forces, the Duke was briefed extensively about the history that surrounds the memorial, and he guided his wife as they passed the resting place of men from Z Special Unit – soldiers who took part in one of the war's most daring operations.

"The Prince was aware of Z force and was very keen to visit and recognise that this was a huge amount of heroic resistance towards the end of the war," British defence adviser Captain Clive Coombes said.
