Empire of Tea - Episode 1

George Orwell described tea as “one of the mainstays of civilization in this country.” But how did this foreign plant become so British? Sathnam Sanghera speaks to Orwell expert Jean Seaton, cultural historian Kate Teltscher, and ramblers with flasks of tea in the Peak District, to try and figure out how and why tea became a national obsession.
