Former British Conservative politician Michael Portillo presents the final installment in a series revisiting the great moments of history to discover that they often conceal other events of equal but forgotten importance.

Yet in truth its impact was a good deal less far-reaching than is popularly believed. Another document, The Charter of the Forest, signed two years after Magna Carta, was the true charter for the common man. Michael Portillo goes in search of this forgotten manifesto for English rural life.
