Jonathan Freedland takes the long view of history looking at the past behind the present. On a farm in Cambridgeshire he compares the current Dairy Crisis with the 1930's Wheat Crisis.

Freedland, accompanied by an agricultural historian, rural affairs correspondent, farmer and an actor whose line about "Accrington Stanley" immortalized the Milk Board, compares both crises. Then as now a global glut in supply led to plummeting prices and failing farms in Britain, smaller farms suffered and farmers were forced to diversify. But what lessons can the dairy industry learn from how the wheat crisis was handled in the 1930's? Answers solicited down on the farm.

Producers Neil McCarthy and Kate Lamble.
