Sue Lawley's castaway in Desert Island Discs this week is Sir Bernard Ingham. For 11 years, one month and five days, almost from when she came to power to the day she left office, he stood shoulder-to-shoulder with Mrs Thatcher. A former card-carrying member of the Labour Party, he became her Chief Press Secretary, adviser and supporter.

He was accused by the media of crossing the line between civil service impartiality and political support on that fateful day in Paris in November 1990, just 36 hours before she lost the leadership election. He'll be telling Sue Lawley about his childhood in Yorkshire, his training as a journalist on the Hebden Bridge Times, his transition to Press Secretary for Tony Benn, Maurice MacMillan and Barbara Castle. In 1979, no-one was more astonished than he when he was headhunted to become one of Mrs Thatcher's closest advisers, and finally one of the most influential members of her team.
