The Duchess of Sussex is to carry out her first solo royal engagement next week, as she attends the opening of a major art exhibition celebrating the Pacific cultures she will soon visit on tour. The event will be a milestone in the Duchess’s life as a member of the monarchy, seeing her at work without the support of her husband or other senior members of the Royal family.On Monday she launched her first charity project, a fundraising cookbook created by women from the Grenfell Tower community, and will host a launch for it on Thursday with the Duke by her side.The 37-year-old former actress has now been confirmed as joining guests on September 25 at the opening of an exhibition of works from the Oceania region, at the Royal Academy of Arts in central London.The Duchess of Cambridge carried out her first solo engagement, standing in for the Prince of Wales at a private fundraising dinner, in October 2011, almost six months after her wedding day. The Duke and Duchess are due to tour part of the region next month, visiting Australia, Tonga, Fiji and New Zealand. The Duchess will be shown art from the four countries during her exhibition viewing.She will meet the exhibition’s curators, artists and descendants linked to the works on display, and view a short performance by Ngati Ranana, a Maori cultural group.The exhibition will be organised around three main themes: Voyaging will look at life on the water as revealed through the stories of indigenous navigation; Place-making will explore the settlement of communities; and Encounter will focus on trade and exchange in Pacific cultures.Oceania at the Royal Academy will open to the public from September 29 to December 10.
