Pupils were given a lesson in politics, prison and faith when former Conservative MP Jonathan Aitken visited Oakham School.
Mr Aitken met pupils studying politics before giving a lecture to more than 140 pupils, parents and staff.
As well as discussing his life in the political arena, he also talked about his experience of being convicted and imprisoned for perjury.
During his lecture, he described the challenges his situation brought, particularly to his faith.
Mr Aitken also held a question and answer session following the lecture.
The Rev Alex Aldous, chaplain at Oakham School, said: “He was an insightful speaker.
“He challenged pupils to think outside the box by using stories from his own life to question how we evaluate another human being in very different social contexts.
“He, personally, was stripped of everything –his marriage, his assets and his freedom – and from the depths of prison he could recognise the redeeming power of Christ to change.
“In short, his talks characterised his humanity, good humour and new-found humility, and you cannot argue against that.”
