Last week, the government announced new plans to scrap water pollution restrictions for housing developments in order to build new homes - some farmers warn that the government is undercutting its own environmental schemes.

And all this week we look at growing herbs in the UK. Presented by Charlotte Smith and produced by Rhiannon Fitz-Gerald.
