It's party conference season, and Farming Today is following what each one is pledging on rural affairs. This week, the Conservatives are gathering in Manchester, and we speak to Thérèse Coffey, the Secretary of State for the Environment and Rural Affairs. As the Scottish Agriculture Bill goes before the Scottish Parliament, Scotland's farming leaders are calling on the UK government to commit an extra one billion pounds to the sector across the four nations as farmers face additional demands to deliver on both food security and the environment.  All week we're looking at root veg. One grower in Norfolk has spent seven years developing his own variety of potato and branding it as a local speciality. The Norfolk Peer is a small salad potato which is sold fresh, in season, but it is also stored and sold all year round, as the Norfolk Keeper. Presenter = Anna Hill Producer = Rebecca Rooney
