Great Yorkshire Show gallery: Princess Anne, celebrity farmers and sweltering stock - all the best photos from day one

One of the warmest Great Yorkshire Shows in memory has begun.

The cattle wash was in high demand as farmers battled to keep their stock cool at the Showground in Harrogate today.

Princess Anne visited the event and celebrity farmers including Countryfile presenter Adam Henson, Cannon Hall Farm's Dave Nicholson and Yorkshire Vet star Peter Wright also attended.

Yorkshire Post photographers Simon Hulme and Tony Johnson were on hand to capture the action.
