The royal couple spent their second and final day in the Swedish capital on Wednesday (31.01.18), and during their visit, they were pictured bonding with five-year-old Princess Estelle and 22-month-old Prince Oscar, who are the children of Crown Princess Victoria and her husband Prince Daniel.

Prince William, 35, and Duchess Catherine - who have two children of their own, Prince George, four, and Princess Charlotte, two, and are expecting a third - met the tots as they joined Victoria and Daniel for tea at their palace in Haga.

After tea, the British royals and their Swedish counterparts visited dozens of children at the Matteusskolan, a combined primary and comprehensive school in the city centre, where Catherine, 36, was spotted giving out high-fives to the youngsters.

Later on in the day, the royals visited the Karolinska Institute, where they joined a discussion on the correlation between mental health in young people and physical exercise.

They rounded off their final day in Sweden with a visit to the Fotografiska Gallery, where William gave a speech about the close bond between Sweden and the UK, and thanked the Swedish royals for their hospitality.

He said: "We are particularly grateful for the hospitality of Their Majesties The King and Queen, and of Crown Princess Victoria and Prince Daniel. We have been very fortunate to have spent much of the past two days in their welcoming company, including at their home in Haga. Thank you for making us feel so welcome. We very much hope we will have the opportunity to repay your generosity in the United Kingdom soon."

William and Catherine will continue their royal tour in Norway, with a two-day trip to Oslo on Thursday (01.02.18) and Friday (02.02.18).
