The Interview

If you are watching cycling's greatest race the Tour de France this year, are you admiring the remarkable strength and stamina of the riders, or privately wondering whether their performance is fuelled by illegal substances? So much elite sport today is tainted by our knowledge of past cheating. Hardtalk's Stephen Sackur talks to David Howman, director General of the World Anti-Doping Agency. Why is it proving so hard to root drugs out of sport?

What does it mean to be black in the United States today? The messages are mixed. An African-American has made it all the way to the White House, but in Barack Obama's America one in three of all young black males is likely to spend time in prison during the course of his life. Stephen Sackur speaks to Bryan Stevenson, a lawyer, rights advocate and founder of the Equal Justice Initiative. Why are America's race-based wounds so slow to heal?

Hardtalk is at Nato headquarters in Brussels to speak to the organisation’s Secretary General, Jens Stoltenberg. In some ways it is just like old times – Moscow is once again seen to pose a threat to Europe’s eastern flank. Nato leaders promise a robust, collective response. But a generation on from the Cold War - are they serious? The western world’s military alliance has a proud history, but does it have a future?

Ukraine is grappling with security and economic challenges, which could bring the nation to its knees. The country needs a new generation of strong, reform-minded leaders - but does it need Mikheil Saakashvili? Hardtalk speaks to the former president of neighbouring Georgia, recently appointed governor of Ukraine’s strategically vital Odessa region. He knows all about confrontation with Vladimir Putin - but is he a credible or wise addition to Ukraine’s hard-pressed government?

Hardtalk speaks to William Schabas, who chaired the commission of inquiry into the Gaza war until he quit under heavy fire from Israel. What does the Schabas saga say about the effort to apply international justice in the Middle east?

Stephen Sackur speaks to writer and publisher Jürgen Todenhöfer, who embarked on one of the most hazardous journeys imaginable for a western journalist. Last December, the 74-year-old German spent 10 days inside the territory controlled by the so-called Islamic State movement. He was taken to the group's base in Raqqa, Syria, and then to their most highly prized asset in Iraq - the northern city of Mosul. He emerged unscathed with a remarkable story. What motivates the jihadist fighters?

A special edition of Hardtalk from Cannes, which is currently hosting the world’s advertising industry. Thanks to the internet, advertising and marketing now have the ability to reach deep into the fabric of our lives. No one has exploited that better than today’s guest – Sir Martin Sorrell, the founder and CEO of the giant advertising conglomerate, WPP. The ad industry is extraordinary powerful, but is it responsible?

Sarah Montague speaks to Bernard Jenkin who has argued for "fundamental change" in Britain's relationship with Europe since he was first elected as a Conservative MP more than 20 years ago. Prime Minister David Cameron is due to meet Europe's 27 other leaders this week but can he secure enough from his negotiations to win over the eurosceptics?

Not since Margaret Thatcher vowed to break the power of organised labour has Britain's trade union movement faced a bigger threat. The new government wants to make it harder to take industrial action. Hardtalk speaks to Frances O'Grady, whose organisation - the TUC - is the collective voice of the unions. Across Europe, in most countries, the number of workers joining unions is in decline. For many of those most in need of support in the work place - have the unions become irrelevant?

Zeinab Badawi speaks to the Sudanese politician Ghazi Salahuddin Atabani. For 25 years he stood beside Sudan’s President Omar al-Bashir as a key adviser and party leader. Then, less than two years ago, he deserted the government and now heads the opposition Reform Now Movement. As a former insider, does he really believe the opposition stand a chance in Sudan?
