Tony Blair served as Prime Minister of Great Britain and Northern Ireland from 1997 to 2007 - the only Labour leader in the party’s 100-year history to win three consecutive elections.

He helped secure the Good Friday Agreement in 1998 bringing peace to Northern Ireland and was a passionate advocate of an interventionist foreign policy, tripling the UK’s foreign aid to Africa, and introducing legislation to tackle climate change.

Since leaving office his work has focused on three areas: supporting governments to deliver effectively for their people, working for peace in the Middle East, and countering extremism through the Tony Blair Institute for Global Change.

On this 300th anniversary of the British PM, he reflects on his time in office, the role of the PM and the challenges facing leaders across the world. He talks to Alastair Campbell, best known for his role as Director of Communications and Strategy throughout his tenure.
