Princes William and Harry have been filmed helping unload sandbags in a private trip to the flood-hit village of Datchet in Berkshire.
Dressed in waterproofs and wellingtons, the royals helped shift heavy sandbags onto the back of an army truck.
The princes were spotted working with the team of 20 members of the Household Cavalry and Network rail staff by a Guardian reporter.
A royal aide told the newspaper that the pair had been working with members of the Army unit this morning in numerous locations and that it was a "private effort" to help.
