The 32-year-old royal hasn't been seen since he left Kensington Palace in London with his wife Duchess Catherine and their 21-month-old son Prince George and newborn daughter Princess Charlotte on 6 May to travel to their home in Norfolk, but will return to his royal engagements next week with a trip to Switzerland.

According to Us Weekly, the visit on Monday (18.05.15) will see him attend two meetings abroad as part of his involvement in the United for Wildlife movement - a foundation created by the Duke and Duchess along with his younger brother, Prince Harry.

William began paternity leave from East Anglian Air Ambulance Service at the end of April after the first section of his training was completed sooner than expected.

A Kensington Palace spokesperson explained: "This is due to a combination of The Duke performing well in the various modules and having very good flying conditions that allowed flight training and assessment to progress more quickly than had been planned."

And although he has been busy with his newborn baby, who is now 12 days old, William is expected to return to training next month.

The statement continued: "His final block of in-work training requires an uninterrupted three-week block of working time and the availability of the new EC145 helicopter that will be used for missions. As he now will not have any further training to complete after returning from paternity leave, he will not return to duties until that time, and will remain on unpaid leave until then."
