Prince William and Duchess Catherine will visit Oslo and Stockholm next year.
The royal couple – who share Prince George, four, and Princess Charlotte, two, and are expecting their third child together – will visit the countries between Tuesday January 30 to Friday February 2 at the request of the United Kingdom’s Foreign and Commonwealth Office.
They will visit Stockholm, Sweden on January 30 and 31 before heading to Oslo, Norway on February 1 and 2.
Details of their full itinerary has yet to be released.
The Duke and Duchess of Cambridge announced they are expecting their third child in April 2018.
A statement issued by Kensington Palace said at the time: "The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in April 2018 …
"Their Royal Highnesses the Duke and Duchess of Cambridge are very pleased to announce that the Duchess of Cambridge is expecting their third child. The Queen and both their families are delighted with the news.
"As with her previous two pregnancies, the Duchess is suffering from Hyperemisis Gravidarum. Her Royal Highness will no longer carry out her planned engagement at the Hornsey Road Children’s Centre in London today. The Duchess is being cared for at Kensington Palace."
Prince George also started at Thomas’s School in Battersea, south west London earlier this year.
A series of tweets on the official Kensington Palace Twitter account read: "The coming months will see The Duke & Duchess & Prince Harry undertake a busy autumn programme as TRH return to royal duties & engagements. Over the course of the autumn, TRH will visit a number of communities, charities and organisations across the UK. TRH will continue to highlight the important work of their patronages, & collectively focus on supporting issues surrounding mental health. (sic)"
