In pictures: The 60th anniversary of the Royal Norfolk Show
More than 1,700 animals will be on display during the two-day Royal Norfolk Show which started earlier. Organisers say the equine and livestock shows are set to be one of the biggest to date with new classes, a record number of "Horse of the Year Show" qualifiers and a record number of livestock entries.
New events for the show's 60th anniversary include a donkey competition and the retrained racehorse "jump challenge".
Prince Edward, the Earl of Wessex, who is president of the Royal Norfolk Agricultural Association (RNAA), will also be attending. Organisers say he "will fulfil a packed programme of visits and presentations across the showground during his two-day stay".
Agriculture, say the organisers, is at the "heart" of the show. Highlights include Knot Farm, a small farm area to commemorate the Stafford family which once lived at Costessey Hall, along with a farming innovations competition and the finals of the Grow Your Own Potato competition for schools.
The Grand Ring will feature the Bolddog Lings Freestyle Motorcross team, the RAF Falcons Freefall Parachute team, the Band of the Brigade of Gurkhas and the Waldburgh Shires Heavy Horse Musical Drive, in which 12 pairs of heavy horses and drays perform to music.
The Royal Norfolk Show is the largest two-day agricultural show in the UK. About 100,000 people visit the show each year.
