Edinburgh-born former lawyer Sir Malcolm Rifkind was first elected as a Conservative MP in 1974. A former Defence and Foreign Secretary, he served continuously as a minister for 18 years under Margaret Thatcher and John Major.

In conversation with James Naughtie, he looks back on his relationship with the 'Iron Lady', meeting Mikhail Gorbachev, the poll tax controversy, Tory Brexit wars and the personal side of political life.
