Francois Pienaar was captain of the South African rugby team when it won the World Cup in 1995. Before the game Nelson Mandela walked into the stadium in Johannesburg wearing the Springbok rugby jersey, which was once seen as a symbol of white minority rule. It came to be viewed as a defining moment for the emerging ‘Rainbow Nation’. Francois Pienaar went on to develop a friendship with Nelson Mandela. George Alagiah asks him whether the hope and optimism generated that day is still alive today.

For the last few years the EU has been under enormous strain. Amid the bail outs, austerity and rising unemployment some Europeans have come to see the EU as part of the problem, not the solution. HARDtalk speaks to Martin Schulz, the President of the European Parliament. He'€™s one of Europe'€™s most powerful advocates of more integration, but is he out of tune with Europe'€™s mood?

Is the stability and unity of the European Union threatened by internal migration?

When Edward Snowden leaked American intelligence secrets the whole world became aware of the extent of US-UK surveillance of global phone and internet traffic. Have the revelations flagged up a corrosive infringement of individual liberty, or undermined efforts to protect the world from terrorism?

Hardtalk speaks to journalist, Glenn Greenwald - the man who broke the Snowden story. His mission, he says, is to hold power to account. Is this a journalistic crusade that's gone too far?

Ukraine had a historic opportunity this week to move toward full integration with the European Union. EU leaders wanted to seal an association agreement which would have drawn one of Europe's largest nations firmly into Brussels' orbit. But Ukraine's president walked away from the deal, in favour of closer ties with Russia. Why? Hardtalk speaks to Petro Poroshenko, Ukrainian billionaire-businessman and former minister. East or West - where do Ukraine's real interests lie?

From genetic engineering to bioscience, human beings are close to acquiring the ability not just to combat disease, but to enhance and perfect our species. But should we seek to do it, or should we shy away from a path that led to Nazi eugenics? Hardtalk speaks to the Australian born, Oxford based medical ethicist Julian Savulescu. Can we trust ourselves to be wise masters of our own biology?

Mental illness is the invisible scourge of modern life, and it comes with a stigma. To admit to depression, or another illness of the mind, has been to risk being labelled as weak, self-indulgent or mad. Ruby Wax wants to change that. She made her name as a comedian and TV entertainer; long experience of depression eventually took her into neuroscience and psychotherapy. Mental illness raises difficult questions, where did she find answers?

What exactly is progressive politics? In the rich world it is identified with the centre left, with a faith in the state's ability to ameliorate the perceived excesses of market capitalism. Hardtalk speaks to Roberto Unger, an influential Brazilian political philosopher who has a much more ambitious take on what it means to be progressive. He calls himself a revolutionary, but is the world - rich or poor - ready for his progressive revolution?
