A "New Deal for Farming" including better trade deals and more public procurement of home grown food - we hear what's in the Labour Party manifesto on farming, the environment and rural communities. It's part of a series of political interviews with the main parties that will run on the programme across the week. Groundswell is the biggest UK event for "regenerative farming" - and around eight thousand people are expected to attend this week's show. But some farmers worry that switching to growing food without relying on chemicals will lead to lower yields and less profit. So what's the solution? And, we meet the seed breeder who produced a variety of wheat called "Champion" which was used by the Lincolnshire farmer who holds the World Record for the most wheat produced per hectare of land.
