Stephen Sackur interviews Katharine Gun. In 2003 she worked at the UK's signals intelligence agency GCHQ. She leaked potentially explosive information about America's covert effort to sway UN diplomats to support the Iraq war.

The Turkish Foreign Minister, Mevlut Cavusoglu, talks exclusively to HARDtalk's Zeinab Badawi in Ankara. Turkey has been condemned for its offensive in northern Syria, but it says it will press on with its operations to flush out what it describes as Kurdish terrorists.

HARDtalk's Stephen Sackur speaks to Alan Semo, UK Representative, Kurdish Democratic Union Party. Donald Trump's decision to pull US troops out of northern Syria has prompted a Turkish military invasion of territory held by Syria's Kurds. The Kurds are now looking to President Assad for military help. The region, once a playground for so-called Islamic State, has been plunged back into chaos. What are his people's options now?

Brexit represents a political gamble played for the highest of stakes. If Britain leaves the EU without a deal there will be significant economic disruption, even the most ardent Brexiteers acknowledge that. But they believe the potential rewards justify the risk. Stephen Sackur speaks to Stuart Wheeler, a successful businessman and lifelong gambler who backed his commitment to Brexit with plenty of his own cash. Has his money given him undue influence over Britain's future?

Stephen Sackur speaks to the singer/songwriter Brett Anderson. His band Suede was hailed as the future of rock and roll back in the early 1990s. Today they are still making music a generation after Britpop ceased.

The Internet was trumpeted as the tech tool to deliver us a golden age of knowledge, freedom and democracy. Now we're in a darker, more cynical place. The digital revolution has generated fears about lost privacy, mass surveillance and systemic misinformation. Stephen Sackur speaks to the President of Microsoft, Brad Smith, about we can ensure our astonishing technological advances are harnessed for good, not harm.

It is tempting to ask what almost two decades of American intervention in Afghanistan have achieved. Even now, the death toll in the Afghan conflict far outstrips the losses in Syria and Yemen. But the grim statistics tell only a part of Afghanistan's story. Stephen Sackur speaks to Kimberley Motley, an American lawyer who went to Kabul in a training capacity and stayed to become a respected litigator fighting for the rights of the abused and the powerless.

Brexit is stress-testing Britain's political and constitutional conventions to the very limit. With prime minister Boris Johnson apparently intent on ignoring the will of parliament and exiting the EU at the end of October, the eye of the Brexit storm is fast approaching. Stephen Sackur speaks to the MP Heidi Allen who quit the Conservative Party earlier this year and co-founded a new pro-remain centrist party, but that bid to break the political mould failed.

Hong Kong has become a cockpit of political protest and sporadic violence as many thousands continue to demand democratic reform. Stephen Sackur interviews Anson Chan, who was the chief secretary of Hong Kong during the handover from British to Chinese rule. She is still close to the centre of the storm, as Beijing now accuses her of fomenting the protest. Is Hong Kong's fragile status quo irretrievably broken?

British Prime Minister Boris Johnson's pledge to take Britain out of the EU on October the 31st is in trouble. Parliament has passed a law requiring him to seek a deadline extension from the EU; so either he negotiates a new exit deal in short order, or he attempts to defy the law. How is this British melodrama being viewed in Europe? Stephen Sackur interviews French MEP and former Europe Minister Nathalie Loiseau. Has EU patience with British indecision run out?

The number of migrants making the sea crossing from North Africa to southern Europe has fallen dramatically in the last two years; tragically, the number of deaths hasn't declined as fast. Humanitarian activists blame the anti-migration policies of EU member states. Stephen Sackur speaks to Carola Rackete, who defied the Italian authorities to land the rescue-ship Sea Watch 3 in Sicily with 50 migrants on board.

Prime minister Boris Johnson's determination to be out of the EU come what may on October the 31st, and his decision to suspend parliament for more than a month starting next week means opponents of a no deal Brexit have just days to thwart him. Stephen Sackur interviews Conservative MP and ardent Brexiteer Peter Bone. Is Brexit about to break his party and Britain's democratic reputation?

Eighty years ago, hundreds of Jewish children were smuggled out of Nazi occupied Europe by train in a covert humanitarian mission which became known as the kindertransport. Stephen Sackur speaks to Dame Stephanie Shirley, who was one of those children. She went on to live an extraordinary life of achievement and philanthropy, blazing a trail for women in business, science and technology.

The online porn industry makes billions of dollars every year, but the big winners are not the performers. Stephen Sackur interviews former porn actress Mia Khalifa, who garnered worldwide notoriety when she appeared in a video wearing the hijab.

Our planet is haemorrhaging natural resources at an alarming rate. Biodiversity is under threat as forests are felled and wild animals are illegally hunted. Stephen Sackur speaks to Lee White, newly appointed Environment Minister in the West African state of Gabon. He is on the frontline of the effort to conserve and protect what remains in a country famed for its tropical forests, elephants and gorillas, but also notorious for systemic corruption and inequality.

Tobacco giant Philip Morris International claims it wants a smoke free world and the phasing out of cigarettes, hailing its new smoke-free products as the future. But Philip Morris International still sells almost 800 billion cigarettes a year.

Donald Trump, the self-proclaimed deal maker extraordinaire, is finding the Korean Peninsula tough going. For all his claims of friendship with the North Korean dictator Kim Jong-un, Pyongyang seems no closer to giving up its nuclear arsenal.

Back in 2015, the nations of the world made a formal commitment to keep global warming below two degrees centigrade. So much for fine words; global greenhouse gas emissions are still rising. The data suggest the planet is warming at an alarming rate. Stephen Sackur interviews Roger Hallam, the co-founder of Extinction Rebellion, a movement dedicated to mass resistance and civil disobedience.

When the Indian Government revoked the special autonomous status of Jammu and Kashmir, it knew outrage would follow; which is why Delhi has the Muslim majority Himalayan territory in a form of lockdown. Troops patrol the streets, hundreds of local politicians and activists have been detained and communications links have been cut. Stephen Sackur interviews the leaders of the Jammu and Kashmir People's Movement, Shah Faesal.

Stephen Sackur interviews prize-winning writer on race and founder of the Anti-Racist Research Centre in Washington, Ibram Kendi. He says the roots of racism run deep and an honest assessment of their strength has barely begun.

The British Government's Brexit strategy can be summed up in Prime Minister Boris Johnson's three-word phrase: 'do or die'. As a deal between London and Brussels appears unlikely, what about the alternative? Stephen Sackur interviews Iain Duncan Smith, former Conservative party leader and ardent Brexiteer. Can Prime Minister Johnson deliver a no-deal exit? And what would it mean for Britain's politics and economy?
