Alan Moore - Graphic Novelist

After the worst mass shooting in US history at a nightclub in Orlando, presidential hopefuls Hillary Clinton and Donald Trump are clashing over the causes. Conservatives used to be united by their shared attitude to god, guns and gays; confident warriors in an ideological battle with liberals. Orlando is another test for those beliefs. Former speechwriter for US president George W. Bush, and lifelong conservative David Frum, thinks the triumph of Trump proves that the power of conservatism is crumbling. Should Republicans embrace change? And should they even consider embracing Hillary Clinton?

Britain's referendum campaign on whether to stay in or leave the European Union is not going quite as Prime Minister, David Cameron, would have wished. He wants a convincing win for the Remain camp on 23 June but the polls suggest it will be very close. Are the Remainers beginning to worry?(Photo: Former Conservative Cabinet Minister Michael Heseltine attends the funeral for Tony Benn, 2014. Credit: Oli Scarff/Getty Images)

Stephen Sackur talks to Chris Grayling, the Leader of the House of Commons in the UK and a senior figure in the campaign to leave the European Union. Any hopes that Britain's decision on whether to stay in or leave the EU would be calm, dispassionate and respectful have been well and truly dashed. In the run up to the referendum on 23 June, the the two camps are kicking lumps out of each other - and the fight is at its bloodiest inside the governing conservative party. Will this political war ultimately weaken Britain and Europe?(Photo: Leader of the House of Commons, Chris Grayling, speaks during a Vote Leave press conference on 31 May 2016.

Stephen Sackur talks to Michael Yardy, former top England one day cricketer and world cup winner in 2010, whose international career ended as a result of mental illness. Elite professional sport is a well-rewarded but unforgiving business. Top performers need a particular kind of mental strength. What happens when they lose it - when self-doubt and depression kick in? Why have so many cricketers suffered from mental torment?(Photo: Michael Yardy of Sussex celebrates his century during the LV County Championship match between Lancashire and Sussex at Old Trafford, 2014.

Stephen Sackur speaks to Tom Fletcher who was appointed British Ambassador to Lebanon at the tender age of 36. Five years on he has just written an operational review of the UK’s Foreign Office. What is the point of the modern day diplomat? Theirs is a world of fortified embassies, chauffeured limousines, and elaborate protocol, but in this globalised internet age, what kind of value do they add? Is diplomacy as we know it dead?

HARDtalk’s Stephen Sackur talks to the President of Costa Rica, Luis Guillermo Solis. They used to call Costa Rica the Switzerland of Latin America; it seemed so much more stable, peaceful and prosperous than its neighbours. But now that image is fading as the country faces a budget crisis, endemic poverty, organised crime and corruption. President Solis came to power promising change, so what’s gone wrong?

Stephen Sackur speaks to Dr Fatih Birol, executive director of the International Energy Agency and one of the world's most influential observers of the global energy market. The price of oil has more than halved over the past two years. That's great news if you're an oil consumer but it's alarming if your priority is to wean the world’s economy off carbon emitting fossil fuels. Does cheap oil make decarbonising the world economy even more difficult?(Photo: Dr Fatih Birol in the Hardtalk studio)
