The Duke of Cambridge is returning to work as a pilot with East Anglian Air Ambulance (EAAA) after taking a break ahead of the birth of his daughter Princess Charlotte.
William took unpaid leave in April following the first phase of his training.
He and his wife Kate welcome the birth of Charlotte early this month and have spent most of the past month away from the public glare at their home, Anmer Hall, on the Sandringham estate in Norfolk with their newborn and son George.
The Georgian country home was given to the couple by the Queen as a wedding present.
William is understood to be in the closing stages of his training to be a pilot with the ambulance team, after which he will transport patients to hospital.
He previously served in the Royal Air Force, most recently as a search and rescue pilot.
He has had several official engagements since the birth of his second child, including awarding actress Sheridan Smith an OBE.
And the Duke, an Aston Villa supporter and president of the FA, watched his club endure a crushing 4-0 defeat at the hands on Arsenal in the Wembley clash.
His return marks the end of a break of almost six weeks from his flying duties.
The EAAA serves the counties of Bedfordshire, Cambridgeshire, Norfolk and Suffolk, an area of 5,000 square miles, and needs to raise £8.6 million this year to continue its service, find out more at www.eaaa.org.uk.
