James Naughtie talks to former US Secretary of State John Kerry about his life and political career.

At his home in Massachusetts, which he represented in the United States Senate for close to 30 years, Kerry discusses his experiences as a naval officer in Vietnam, how he felt the pull of politics, and what he attempted to achieve. Reflecting on the 2004 presidential election campaign, where he was the Democrat nominee against President George W. Bush, Kerry says it was the first 'fake news election'.

In four years as President Obama's Secretary of State, Kerry travelled more than a million miles around the world, and he discusses his experiences negotiating the Iran Nuclear Deal, the decision not to strike Syria, and his friendship with Benjamin Netanhayu.

And on domestic politics, Kerry has some striking advice for his party after losing the 2024 presidential election.
