More than 20,000 people were expected through the gates of the Thame and Oxfordshire County Show at Thame on September 18.

The show attracts spectators and competitors from all over the country for its top class show jumping competitions and agricultural displays.

Among the visitors will be Norfolk farmer Tony Martin, who was released earlier this year after serving two-thirds of a five-year jail sentence for shooting dead a 16-year-old burglar.

He will be discussing rural crime with BBC Radio Oxford presenter Bill Heine.

Mr Heine will also be talking to Oxfordshire County Councillor Lord Bradshaw, who lives in Wallingford.

The show is primarily a showcase for the farming industry --which has had a rough time because of various problems including mad cow disease and foot and mouth disease.

Show secretary Mike Howes said: "Despite everything the farmers have come up trumps with their exhibits this year, and of course we are delighted to see cattle and sheep back after the absence because of foot and mouth.

"The show has something for everyone -- animals, birds, crafts, classic cars, country sports and motor cycle display thrills as well as music.

"It promises to be a bumper day."

The show is the biggest one-day agricultural show in England and has its own ground alongside Thame ring road.

The NFU food and farming roadshow is coming to the show to raise awareness about British food.

Visitors will be able to talk to farmers, milk the roadshow's model cow, view day-old chicks and enter a quiz on British food.

Lancashire farmer Johnny Ball, who is presenting the show, said: "Two thirds of people have never met a farmer. So the NFU roadshow provides a valuable chance to meet a real farmer or grower from your home county."

The roadshow will be parked in the livestock area (horse rings three and four/trade block E) in the south-western corner of the showground, located off the A418 road.
