’Why do we do it? This is the best job in the world.’

In the wake of the huge farmers' protest in London on 10 February, Rob Lyons talks to two Cumbrian farmers, John Shaw and Richard Kerr, along with their accountant Paul Benson, about the state of farming in the UK today.

• Why farmers are so angry about the Labour government's inheritance tax changes
• The existing difficulties with making a good living from farming, particularly the power of supermarkets
• Why it is unfair to blame sheep and cattle farmers for climate change
• The failure of many politicians to understand why a farm is more than just a business
• Why, despite all the difficulties, they continue to want to farm - if the government will let them.
