Asked by ITV News whether he was enjoying helping in flood-hit Datchet, Prince Harry replied: "Not really with you guys around".
The royals were spotted on their "private" mission to help residents by journalists this morning and they have since been followed by reporters and photographers as they continue their visit.
Earlier, Prince William suggested that reporters should "come and help instead of throwing cameras around" after he was pictured loading sandbags in the flood.
