The Duke and Duchess of Cambridge will visit Northern Ireland on Tuesday.
William and Catherine are attending a garden party at the Royal residence at Hillsborough Castle, Co Down.
The region’s secretary of state has hosted the event annually since 1984.
Around 2,500 guests have been invited by Theresa Villiers this year, with attendees drawn from a wide cross-section of Northern Ireland society, including the voluntary and community sectors, local charities and youth organisations.
The occasion will be only the second time the Royal couple have visited Northern Ireland together.
The last time was in March 2011, only weeks before their wedding.
On that occasion Catherine tossed pan cakes at Belfast City Hall and hammered in fence posts at Greenmount Agriculture College in Co Antrim.
