In 1989 Thatcher faced the most serious crisis of her career - her Cabinet was split over her refusal to change economic policy and her Chancellor and economic adviser resigned. By 1990 it was all over but Thatcher had few regrets.

"I never lost an election and I never had a majority lower than 45… you can't live an if only life, I was there for eleven and a half years, they were the eleven and a half most exciting years of my life. They were exciting for Britain, they brought Britain's reputation up, Britain meant something to the world."

She left the House of Commons in 1992, and now sits in the Lords as Baroness Thatcher.
