The second programme examines how and why the interview that stunned the nation and threw the monarchy into a constitutional crisis took place and those who were present describe what happened in the room when the interview was recorded.

This programme features new footage highlighting the serious rift at the very top of the Corporation over the interview as Marmaduke Hussey, who was then chairman of the BBC, in an archive interview which has never previously been broadcast, speaks about the fact he was not initially informed about the interview by director general John Birt.

The programme also examines the interview's impact on the monarchy and on public life a quarter of a century on.
