The 35-year-old royal - who has Prince George, three, and Princess Charlotte, 20 months, with her husband Prince William - will meet air cadets from the Bedfordshire and Cambridgeshire Wing Air Training Corps, who will be taking part in a skills development camp in their school half-term.

A statement from Kensington Palace reads: "The week acts as an initial 'camp experience' for cadets who are in their first six months of membership. Her Royal Highness will join the cadets as they view a Tutor aircraft, and participate in a personal development training session."

The Duchess of Cambridge will also be given the chance to pilot her own aircraft in a flight simulator.

The visit marks the Duchess' third visit to the RAF Air Cadets since she became Royal Patron and Honorary Air Commandant of the Air Cadet Organisation after taking over from Prince Philip, the Duke of Edinburgh.

Whilst Duchess Catherine and Prince William won't be spending Valentine's Day together, the couple will be able to spend more time together in London after it was recently revealed the 34-year-old royal is quitting his job with the East Anglian Air Ambulance this summer.

He said in a statement: "It has been a huge privilege to fly with the East Anglia Air Ambulance. Following on from my time in the military, I have had experiences in this job I will carry with me for the rest of my life, and that will add a valuable perspective to my royal work for decades to come. I would like to thank the people of East Anglia for being so supportive of my role and for letting me get on with the job when they have seen me in the community or at our region's hospitals.

"I would especially like to thank all of my collegues at EAAA, Babcock and Cambridge Airport for their friendship and support. I have loved being part of a team of professional, talented people that save lives every day. My admiration for our country's medical and emergency services community could not be any stronger."
