In the winter of 1962-63, the UK experienced a different kind of lockdown as freezing temperatures and ten weeks of snow kept people trapped at home in one of the coldest winters on record. Today, I'm joined by Juliet Nicolson who was eight years old at the time and has written a book all about that bitterly cold winter. She argues that the big freeze not only reflected the threat of the cold war but also beneath the frozen surface new ideas were beginning to stir which would lead to the massive cultural and societal shifts of the 1960s.
