Britain's Prince William and his wife Kate flew to Norway on the final leg of a Nordic trip on Thursday, and stepped out onto a red carpet laid out over a blanket of snow. They were greeted by the country's Crown Prince Haakon and Crown Princess Mette-Marit at Oslo's Gardermoen Airport and went on to meet well-wishers waving Union Jacks in the winter cold. William and Kate - expecting their third child in April - toured a children's sculpture park at the start of their two-day trip and were due to visit the Ski Museum, dedicated to Norway's national sport. They were also expected to meet students to discuss mental health - an issue that William and his brother Harry have campaigned on in the past. _________________ Read more: <strong><a href="https://www.thenational.ae/world/europe/prince-harry-and-meghan-markle-royal-wedding-to-take-place-in-may-at-windsor-castle-1.679679">Prince Harry and Meghan Markle: Royal wedding to take place in May at Windsor Castle</a></strong> <strong><a href="https://www.thenational.ae/lifestyle/trump-wishes-royal-couple-well-amid-uncertain-wedding-invite-1.699455">Trump wishes royal couple well amid uncertain wedding invite</a></strong> <strong><a href="https://www.thenational.ae/lifestyle/buckingham-palace-announces-princess-eugenie-s-engagement-1.697647">Buckingham Palace announces Princess Eugenie's engagement </a></strong> _________________ Prince William, second-in-line to the throne, is also a relative of Norway's King Harald, as both descend from Britain's Queen Victoria.
