Black Panther star Daniel Kaluuya has already won BAFTA's Rising Star award and now he's been nominated for a Best Actor Oscar. The 28-year-old Londoner is up against acting giants Daniel Day-Lewis, Gary Oldman and Denzel Washington, having been shortlisted for his role in the satirical horror movie Get Out. Raised by his Ugandan mother, who remains an inspiration, Kaluuya grew up on a council estate in North London. He first came to public attention as a teenager, when he wrote and performed in the hit television series, Skins. But he's been acting and writing from an early age, having won a play-writing competition when he was nine and impressed talent spotters when he was still at school. Mark Coles talks to those who recognised and nurtured the young Kaluuya's talents, including his A level drama teacher Jo Fenton, the co-creator of Skins Bryan Elsley, playwright Roy Williams and the director of his forthcoming film Widows, Steve McQueen.

He's been called the government's "real Mr Brexit", but is little known outside Whitehall. Mark Coles asks who is Oliver Robbins, the Prime Minister's right hand man for the Brexit negotiations? In the last few months Robbins' role has grown, taking the lead on negotiations with Brussels often without the Brexit Secretary, David Davis. This has led some to question whether a senior civil servant should be given so much power.He had a meteoric rise, becoming Tony Blair's Principal Private Secretary, the most senior civil servant at Number 10, aged only 31. He is almost universally admired by those who've come across him for being able to distil huge amounts of information quickly, keeping calm under pressure, and having a sense of humour. He is popular in Brussels, where his interlocutors appreciate that he is straight with them, and that he "doesn't lie". The consummate mandarin and public servant, not even long-term friends know where he actually stands on politics or Brexit. And he's managed to keep a low profile, despite his role. Producer: Arlene Gregorius.

This week the Home Secretary Amber Rudd announced that Sara Khan will lead the newly created Commission for Countering Extremism - an appointment which was not welcomed with blanket approval, with some sections of the Muslim community calling on her to quit. Sara Khan is the co-founder of Inspire - a counter-extremism and human rights organisation engaging with Muslim women, which has also engaged with the government's Prevent scheme. The counter-extremism programme has proved controversial, with critics claiming it unfairly 'spies' on the Muslim community - but Sara Khan has been a vocal supporter, saying it is vital tool in tackling terrorism at its root. This has put her at odds with some British Muslim organisations, and has also led to vicious online abuse and accusations that she is a 'house Muslim' and a government stooge. This criticism has re-emerged in light of her new appointment, with questions about her experience and whether she really qualifies for the role.Becky Milligan charts Sara Khan's life growing up in Bradford, speaking to old friends who worked alongside her in her early advocacy work as a leader in a prominent British Muslim youth group and charts the road which has taken her to a prominent role in central government.

It's been a tumultuous week in Iran.Thousands of protestors in more than twenty towns and cities taking to the streets to demand economic and political change. On the programme this week, we update a profile we did of Hassan Rouhani when he first became President of Iran back in 2013. Regarded as more liberal than some of his predecessors - and now in his second term as President - he faces the unenviable task of trying to balance the demands of the Iranian people who want better living conditions with the religious establishment which still wields ultimate power. Meanwhile, lurking in the wings, is US President Donald Trump - threatening to tear up a 2015 deal that waived sanctions in return for Iran reigning in its nuclear programme. Mark Coles hears from Iranian journalists, political analysts and some of the President's former colleagues as we get to grips with where he's come from and what his future may be.
