Jonathan Freedland takes the long view of the Catalan government's recent bid for independence and compares it with a moment in 17th-century Cornish history.

Jonathan Freedland compares the Catalan government's recent bid for independence with a moment during the English Civil War when the military commander, Sir Richard Grenville, devised a plan to gain more autonomy for Cornwall. Jonathan and his guests visit historic locations in Launceston, the ancient capital of Cornwall, where this story took place.

With historian Mark Stoyle, Professor of Early Modern History at Southampton University; Sebastian Balfour, Emeritus Professor of Contemporary Spanish Studies at the London School of Economics; Loveday Jenkin, councillor for Mebyon Kernow, the Party for Cornwall; and actor Beatie Edney who played Prudie in the Poldark.
