The Duke and Duchess of Cambridge were the royal guests of honour at the Secretary of State for Northern Ireland's garden party in Northern Ireland on Tuesday afternoon. The royal couple were among 2,500 guests at the party, hosted in the stunning grounds of Hillsborough Castle.
Prince William and Kate arrived shortly after 4pm to cheers from the crowds of fellow guests. They were led onto the steps of the grand residence by Secretary of State Theresa Villiers, before going to mingle with guests in the gardens.

Kate opted to wear a recycled Day Birger coat for the occasion, completing her look with a hat by Lock & Co and the Irish Guards brooch. Meanwhile William wore a navy suit and blue tie.
The Secretary of State for Northern Ireland has hosted the garden party annually since 1984. Guests are invited in recognition of their work with charities or within their communities, and a royal guest of honour attends each year.

William and Kate's appearance at the party comes just hours after they visited the US Embassy in London to sign a book of condolences for the victims of the nightclub shooting in Orlando. The royals looked sombre as they were greeted by the US Ambassador in London, Matthew Barzun, before adding their comments.
After signing, the Duke and Duchess spoke with reps from the US embassy's LBGT network GLIFAA. As a mark of respect Kate wore a knee-length black and white dress teamed with a cropped black blazer.
Their message read: "With our deepest condolences and with our thoughts and prayers to all those affected. William, Catherine."
