The Duke and Duchess of Cambridge help a veteran back up onto his feet after he fell over on their visit to Stewards Academy in Harlow, Essex.
The Duke of Cambridge came to the aid of the Queen's representative in Essex when he took a tumble during a royal visit.
William and others rushed to help Jonathan Douglas-Hughes, vice lord-lieutenant of Essex, when he appeared to slip on wet pavement.
The Duke and Duchess had just arrived at Stewards Academy in Harlow for a visit when the mishap happened.
Mr Douglas-Hughes, who was wearing his ceremonial uniform complete with sword, fell backwards as the Duke was introduced to local dignitaries.
A gasp went up from around 30 well-wishers as he landed on his back and he was helped to his feet by William and others.
Mr Douglas-Hughes turned to William and said "Sorry about that", and the Duke replied "No, it's all right".
