The Duke and Duchess of Cambridge are this afternoon attending the annual garden party at Hillsborough Castle in Co Down.

Prince William and Catherine are joining about 2,500 guests at the event which is being hosted by the Secretary of State Theresa Villiers.

The visit is only the second time the Royal couple have visited Northern Ireland together.

Their previous visit was in March 2011, weeks before their wedding.
