The Kensington Palace announced Wednesday that Kate Middleton, Prince William and Prince Harry will host a special tea party at the Buckingham Palace "to honor the children of those who died serving in the Armed Forces." The event, which is called "Party at The Palace," will be held on May 13.

The event will feature "live performances, various stalls, games on the lawn and the chance to explore the gardens" of the Buckingham Palace. Invitations for the party will be sent this week to children aged below 18 years. Charities such as the Child Bereavement UK will also attend the event.

"The Duke and Duchess of Cambridge and Prince Harry have arranged the event as a way to acknowledge and honour the fact that a number of young children have had to come to terms with the loss of someone very close to them at a young age, having lost a parent in Armed service to the country," the palace said in a statement. "Their Royal Highnesses hope the event will provide an opportunity for these children to broaden their support networks amongst other families with similar experiences."

The Kensington Palace revealed last month that the Duke and Duchess of Cambridge will focus on more royal duties after they move to London later this year. The royal couple will be relocating from their Norfolk country home, Anmer Hall, to settle in the Kensington Palace.

The palace also announced Tuesday that Middleton will visit Ronald McDonald House Charities in London on Feb. 28 to open their new house for the families of children being treated at the center.

Prince Harry, who is the patron of England Rugby, will attend the rugby team's training session at Twickenham on Feb. 17.

On Tuesday, the duchess made her third visit to the RAF Air Cadets of Royal Air Force Wittering since Prince Philip, the Duke of Edinburgh, passed his patronage to Middleton.
