Kate also disclosed she had tried to show her older children, 5-year-old Prince George and 3-year-old Princess Charlotte, the festive treats laid out for military families at Kensington Palace for yesterday's party when they arrived home from school and nursery - but they were too late.

The couple are flying to RAF Akrotiri in Cyprus on Wednesday where some of the loved ones of the families they met are based, and will take with them a collection of early Christmas presents for the RAF personnel.
"It's sad we won't be home for Christmas, but to get that personal message from them with the duke and duchess is lovely".
