The first ever Countryfile Live took place in the magnificent grounds of Blenheim Palace in Oxfordshire - four days in the sunshine celebrating the best of the British Countryside. Matt kicks the programme off with a whistlestop tour of the show, mixing and mingling with exhibitors and visitors, and he calls in at the Craven Arms, Countryfile Live's very own pub.Ellie goes behind the scenes to see what goes into setting up a show on this scale, and she also grabs a quick chat with the Duke of Marlborough, Blenheim's owner, to find out what it's like having such a big show in your garden.Anita steps away from the showground to get up close to some truly magnificent oak trees, many of them more than a thousand years old. John takes to the water to see how ducks are helping restore Blenheim's beautiful ornamental lakes, while Tom and Adam go head to head at the timbers sports arena in a test of strength and speed.And Charlotte Smith looks at what might happen to British foods protected under EU law and catches up with some producers who are worried they will lose a vital protection and others who see a real opportunity.
