Prince William will begin his last shift as an air ambulance pilot this afternoon before moving on to life as a full-time member of the royal family.
The Duke of Cambridge announced in January he would be ending his career with the East Anglian Air Ambulance (EAAA), and has clocked-up more than two years flying medical crews to emergencies from a base at Cambridge Airport.
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.
Throughout his service William has been based out of Cambridge Airport, as part of a team including specialist doctors, critical care paramedics and pilots providing emergency medical services across Bedfordshire, Cambridgeshire, Norfolk and Suffolk.
A statement issued at the time by Kensington Palace said William and Kate wanted to increase their official duties on behalf of the Queen and their charity work, which would mean more time in London.
The Duke of Edinburgh has announced he will step down from his public duties this summer, which is likely to see all members of the monarchy carrying out more engagements in support of the Queen.
The Duke said in the statement in January: "It has been a huge privilege to fly with the East Anglian 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."
