The Duke of Cambridge has begun his final shift as an air ambulance pilot.
Prince William smiled and joked with colleagues as he posed for a group photo ahead of the shift.
He has clocked-up more than two years flying medical crews to emergencies from a base at Cambridge Airport while working for the East Anglian Air Ambulance (EAAA).
Following his final air ambulance shift, the Duke will move on to life as a full-time member of the Royal family.
A statement issued by Kensington Palace earlier this year said William and Kate wanted, as they had in previous years, to increase their official duties on behalf of the Queen and their charity work, which would mean more time in London.
The Cambridges are expected to spend more time at their London apartment at Kensington Palace, rather than their Norfolk property Anmer Hall, as their four-year-old son Prince George will begin school in the capital in September.
The Duke joined EAAA as a pilot in March 2015 and, after completing an initial period of job specific training involving simulator, aircraft and in-flight skills training, he began piloting his first operational missions in July 2015.
Captain Kelly, who is working alongside the Duke on his final shift, said William had made a "fantastic contribution" to the team and it was an "absolute pleasure to have him on board".
Patrick Peal, chief executive of the East Anglian Air Ambulance, said: "He really will be missed because he's a terrific pilot, he's a great guy to have around, he's been really good at scene and that's the feedback I get from all of our clinical teams and he's just been a great person to have as part of East Anglian Air Ambulance."
