'I stole a bit of Hitler's desk'

Joy Hunter started working as a secretary in Whitehall in 1944 and was quickly moved to the Cabinet War rooms.

Her top secret work saw her accompany Winston Churchill to the Potsdam conference in Berlin at the end of the war, where she met Soviet leader Joseph Stalin and America's President Truman.

After years of keeping her wartime experiences secret, Joy has agreed to be interviewed by her great-granddaughter for a new book Voices From The Second World War.

Here she takes her great granddaughter Chloe for a tour of her old workplace, Churchill's War Rooms.
