A final look back at some of the encounters and moments that have encapsulated the programme’s commitment to rigorous, well-researched interviews with people in power.

Ahead of HARDtalk’s closure, at the end of this month after 27 years, here’s a chance to look back at some of the most memorable interviews of the programme’s early years. It’s an extraordinary archive featuring interviews with Donald Trump, Nelson Mandela, Nina Simone, Robin Williams and Martha Gellhorn.

Stephen Sackur speaks to Reid Hoffman, the tech billionaire who co-founded LinkedIn and is a prophet of positivity about Artificial Intelligence.

Another chance to hear Stephen Sackur’s 2014 interview with Allen Ault. As the former commissioner of corrections in the US state of Georgia, Ault was responsible for state-sanctioned executions. He organised the killing of criminals until he could stand it no more. What made him leave his post and take up the campaign to end the death penalty?

Stephen Sackur is in Frankfurt for an exclusive interview with Christine Lagarde, president of the European Central Bank. Donald Trump has triggered what could become a global trade war and has prompted European governments to make massive new defence spending commitments. Is the European economy capable of withstanding Trump 2.0?

Stephen Sackur is in Paris to talk to former Prime Minister of France Dominique de Villepin. With Donald Trump in the White House, the alliance between the US and Europe’s democracies looks fragile. Is Europe capable of becoming a superpower in its own right?

Stephen Sackur is in Germany to speak to Niklas Frank. His father was Hans Frank, the Governor General of Nazi Occupied Poland during the World War Two. He was convicted of war crimes and crimes against humanity at the Nuremberg trials and executed in 1946. Niklas Frank tells Stephen Sackur he 'despises' his father and does not want Germany to forget the crimes of his father and the legacy of the Nazi era.

Stephen Sackur speaks to Roger Carstens, former US Presidential Envoy for Hostage Affairs. Did the deals he strike from Russia to Iran risk making the problem worse?

Stephen Sackur speaks to the UN Commissioner for Human Rights Volker Türk. As conflicts destroy millions of lives around the world, are we sleepwalking into a dystopian future?

Stephen Sackur speaks to the dissident artist Badiucao, whose cartoons and drawings challenge President Xi Jinping and the Chinese state. He lives in exile in Australia, but does that mean he’s beyond Beijing’s reach?
