Buckinghamshire Lord Lieutenant Sir Henry Aubrey-Fletcher was at the show with his wife Lady Sara.
As a vice president of the County Show Sir Henry is a regular visitor, and he enjoyed walking around the showground on Thursday to admire the stalls and sideshows.
Lady Sara said: “You get everything at a show like this. I’m married to a farmer so I like to see the animals. Henry likes the machinery.
“I can’t imagine anyone having anything negative to say, it’s such a marvellous day out.”
