Brexit negotiations between the EU and the UK are months away. And - as we keep hearing - there will be no discussion before notification (of the now infamous Article 50).But we do know who will represent the EU in those negotiations: the French politician Michel Barnier, who met his counterpart David Davis this week.Born in the Savoie region in south-east France, Barnier has been a committed Gaullist since he was a teenager. At 27 he made history in France by becoming the youngest MP ever elected. And in 1992 he took great pride in bringing the Winter Olympics to his region.His allies say he is a reasonable, sensitive negotiator. His critics tell us he can be self-important and cold. Everyone agrees he will be fiercely committed to defending the EU's interests in the complex Brexit negotiations ahead.Presenter: Becky Milligan Producers: Smita Patel and Alex Burton.

On Profile this week, Mark Coles, examines the life and career of Stephen Bannon - dubbed by some as the 'most powerful, most dangerous political operative in America today'. A former US Navy engineer, investment banker and Hollywood producer, for the past four years he's been the driving force behind Breitbart News - a populist, at times deliberately provocative right wing news website. In August, he was drafted in to oversee Donald Trump's then faltering presidential campaign.Now, with Trump heading to the White House, he's been appointed the President Elect's new Chief Strategist. Democrats and civil rights groups are appalled. They accuse Bannon of creating a platform for far right views, fostering racism and anti-semitism.Nonsense, say his supporters. He's simply a patriot, fed up with the way his country has been governed in the past by progressive liberal elites.

To some, she is a saboteur of democracy, a woman using her massive wealth and friends in high places to subvert the judgement of 17.4 million voters in the European Union referendum. To others, this is a woman of unimpeachable principle, fighting to protect a cornerstone of the unwritten British constitution. With the Supreme Court now set to decide on whether Article 50 can be invoked without a vote in Parliament - thus setting Brexit into motion - we ask, who is Gina Miller, the woman behind the legal bid? Well, she has certainly had an interesting life. Born in Guyana, this thrice-married 51-year-old now runs an investment firm, by way of modelling and plentiful philanthropy. Never one to duck a scrap, she has picked fights in the lofty world of high finance and the altogether milder waters of the third sector. At the end of a week that has seen her become the target of both fulminating newspaper headlines and online abuse, we learn about the formative years that thickened up Gina Miller's skin before the onslaught. School friends, Britain's richest plumber and husbands number two and three are among our witnesses; the future of the country is at stake. Mark Coles profiles Gina Miller.

An entrepreneur who helped found Britain's first online bank. A philanthropist who fled Idi Amin's Ugana and is now on a mission to track down the undiscovered Albert Einsteins of Africa. He embarked on a search to find a long-lost sister in Uganda after thirty years; he once rocked an 'impressive' Afro; his backers number a former head of MI6, and during his honeymoon in Mexico he sneaked away from his wife to attend a maths conference. Oh, and he's hell-bent on making it into space. You've possibly never heard him, but he's just been named the most influential black person in the UK. Becky Milligan profiles Tom Ilube.

Samsung started out as a tiny exporter of dried fish. Today it's one of the world's biggest tech giants; the family-run business accounts for about a quarter of South Korea's entire GDP.This week Samsung was forced to stop production of its new Galaxy Note 7 smartphone after a number of them apparently exploded or caught fire. Samsung's chairman Lee Kun-Hee - son of the firm's founder - saw the value of his company plummet. You'd think he'd be fuming. But he hasn't been seen since he suffered a heart attack in 2014. Some in South Korea think he could be dead. Mark Coles tells the story of Lee Kun-Hee - one of the world's most enigmatic and fascinating business leaders.Researcher: Kirsteen Knight Producer: Smita Patel.

British Professor David Thouless won this year's Nobel Prize for contributions to the field of topology. Two other British physicists, Professor J. Michael Kosterlitz and Professor Duncan Haldane shared the award. Of course the physics is rather complicated, you don't win a Nobel prize for discovering something obvious, but put simply, David Thouless worked out a way of predicting how a material will behave using maths.In this programme, though, we'll focus on the man himself. Who is David Thouless and how did he spend his time when he wasn't thinking about equations? We'll hear about the treats he liked as a school boy during the war, about family holidays from his son, Michael Thouless, himself a Professor of Engineering and we'll also hear that things in the real world didn't often go as smoothly as planned...Audio from the Hubbard Theory Consortium 50th Anniversary Lecture used, with thanks.Producer Smita Patel & Researcher Phoebe Keane.

When Theresa May became Prime Minister she appointed Fiona Hill and Nick Timothy as her joint Chiefs of Staff. It's a role first imported from the US by Tony Blair, when he brought in Jonathan Powell to help oversee the day-to-day running of government. The position puts Timothy and Hill at the heart of decision-making inside Number 10. So who are they? And how much influence do they really have? Mark Coles reports.Producer: Ben Crighton.
