The Pyrenees with Michael Portillo

Michaels Pyrenean quest continues with the physical challenge of the French High Pyrenees, which he enters at the Cirque du Gavarnie, a 1,700-metre-high wall of limestone forming a natural amphitheatre. He struggles on across the snowy Plateau de Saugué to meet Marion Clignet, a French Olympic cycling champion who refused to let her epilepsy curtail her career, as well as finding time to reflect on his time as defence secretary, and on the current war in Europe.

For the final leg, Michael is back in the Catalonian Pyrenees for a deeply personal journey. In 1939, his father Luis Gabriel Portillo Perez fled through these mountains as a political refugee from the Spanish Civil War. At the tiny village of La Vajol, where many refugees headed to cross the border into France, Michael meets Margaret, some of whose family escaped through here.
