William the Marshal is one of the men responsible for the Magna Carta as we now know it. His seal is on the re-issuing of the charter in 1217 by Henry III, in his role as Regent for the king. His statue stands in the House of Lords behind the monarch's throne defending the monarchy as he did in life.
Mud Sweat and Tractors is a four part series about the changes in farming in Britain over the last century or so. It split it up into four areas - milk, horticulture, wheat and beef - and treated each as a separate story, so each episode seemed quite self-contained. Each time there were two or three farming families chosen who had photographs and video footage stretching back to the 1930s. So they made good case studies and could talk about why they or their Dad or Grandad had made particular decisions at particular points.
