Duchess of Cambridge Kate Middleton attends memorial service at end of her birthday week

The Duchess of Cambridge has ended her birthday week with a surprise visit to a memorial service in Sandringham, Norfolk. She attended a service honouring those who died in the Gallipoli campaign during the First World War.

Kate Middleton, who turned 34 on 9 January, first attended a morning service at St Mary Magdalene Church in Sandringham with her sister Pippa, brother James, mother Carole and father Michael. She later appeared with Prince William to join the Queen and Duke of Edinburgh in the laying of a wreath at the memorial service on the Royal Family's Sandringham estate.

William and Kate had not been expected to attend the service, so their appearance was a surprise. It's thought that the couple spent Kate's birthday at dinner together.

Earlier in the week, the young royals took their two-year-old son George to his first day at nursery school – a Montessori school near the family home in Norfolk. It was also announced yesterday that Kate would be joining William on a tour of India and Bhutan.
