Dover to Lewes

S7, E6: Beginning in the port of Dover, Portillo takes a plunge into the English Channel, inspired by the example of the first person to swim the Channel. A miniature steam train, one third the size of a conventional locomotive, conveys him from Romney Marsh to Dungeness. In Eastbourne, he learns how the 7th Duke of Devonshire managed to market the town's attractions to the refined upper-crust of Victorian London. Finally, Portillo attends the Glyndebourne opera festival on the South Downs.
