The Home Secretary, Theresa May, is centre stage as she deals with the aftermath of riots across England which have shocked the country and led to the recall of Parliament. The police are under scrutiny for their tactics and performance in London particularly, with reported tensions arising between the Home Secretary and the Met Commissioner. May is a politician who's not afraid to challenge the existing order - and speak the unspeakable. Last year, she told the police that they need to cut their spending and re-organise the way they work. As the chair of the Conservatives in the early 2000s, she said the party was perceived by the public as the "nasty party." It was a start of the rebranding of the Conservatives.The daughter of a clergyman, she attended an independent convent and a number of state schools before going to Oxford. After graduating, she joined the City - working for a time at the Bank of England. She took the hard route into politics - starting off stuffing envelopes in a constituency office before being elected as a councillor in the London Borough of Merton where she spent the best part of a decade.She has a reputation for being focussed on the job and having a Thatcheresque work ethic with few outside interests. Simon Cox profiles Theresa May, one of only four women to hold the key offices in British politics.

When Iran makes the news it is often that country's flamboyant and provocative president Mahmoud Ahmadinejad who finds himself under the spotlight. But the man who wields real power in Iran is not Ahmadinejad, nor was it any of his predecessors as president. Instead it is the man who has served as the head of the country's religious structure since 1989, the Supreme Leader, Ayatollah Ali Khamenei.The Ayatollah owes his rise to power to two men - his predecessor as Supreme Leader, Ayatollah Ruhollah Khomeini and the previous president, Hashemi Rafsanjani. Ayatollah Khamenei has been a cleric for most of his life, beginning as a religious scholar in the city of Mashhad at the tender age of 11. He served several terms in jail as a result of his religious convictions during the secular dictatorship of the Shah. His rise to power began with the revolution of 1979 that turned Iran into the Islamic Republic. Khamenei became, first president, a post with relatively little power, and his election as Supreme Leader after the death of Khomenei was a surprise to all. Many believe this was engineered by Rafsanjani to allow Rafsanjani himself to remain in control.But Khamenei has gradually made himself the most powerful man in Iran - and he's done so by recruiting the Revolutionary Guard to his side. There are those who say that far from a religious dictatorship, Iran is in fact a military dictatorship. But Ali Khamenei is 72 and with 70 per cent of the Iranian population having been born since the revolution, it's not clear that the post of Supreme Leader will survive his death.Producer TIM MANSEL Presenter JAMES REYNOLDS.

With a year to go until London 2012 Shari Vahl profiles John Armitt CBE, Chairman of the Olympic Delivery Authority and charged with delivering the £9bn project on time and budget.

There were cheers and jeers in the House this week when Elizabeth Filkin was named as head of the enquiry to advise on cleaning up the relationship between the Met and the media following the hacking scandal.As former Parliamentary Commissioner for Standards she challenged vested interests at Westminster, until she was 'hounded out' by MPs in 2002 after questioning the probity of some of their number. She took on Keith Vaz - who this week chaired the Home Affairs Select Committee's questioning of recently resigned Metropolitan Police Commissioner Sir Paul Stephenson - during her investigation into his links with the Hinduja family and accused him of deliberately trying to thwart her enquiries.Supporters describe her as "fair but firm... someone who cannot be bribed, bought or bullied."Filkin doesn't come with the typical background for a Government-appointed inquisitor. She is a former community worker, having worked in the London Borough of Brent back in the 1970s. She went on to to be an academic, as well as Chief Executive of the Citizens Advice Bureau.Now over 70, in recent years Elizabeth Filkin may have been out of the limelight, but as Shari Vahl reports, her antecedence suggests she's someone who wants to get at the truth - and isn't too concerned who she upsets along the way.

Rupert Murdoch is the head of News Corporation and at the centre of the political and public storm over phone hacking and the payment of police officers. Steve Hewlett profiles the 80 year old whose high risk and audacious business gambles built an empire, but is now seeing the alleged high risk behaviour of some of its former employees threaten to undermine it. Producer: Nicola Dowling.

Jonathan Maitland profiles Nick Davies, the investigative journalist behind the story of the News of the World phone-hacking allegations that are dominating the headlines. Nick Davies decided to become an investigative journalist after he saw the film All the President's Men, about the US journalists Bob Woodward and Carl Bernstein who revealed the Watergate story that brought down president Richard Nixon. Thirty-five years later, Nick Davies is considered one of Britain's top investigative journalists. He has broken numerous stories, mostly for the Guardian newspaper. His scoops include the story about the nurse turned serial child murderer, Beverley Allitt, and the recent Wikileaks revelations. He has written several books, including Flat Earth News. In this book he accuses many British newspapers of what he calls "churnalism", churning out stories based entirely on PR, press releases or wire copy, without further fact-checking. This did not make him the most popular man in Fleet Street, but he is one of the most respected. He is a passionate, driven, and obsessive journalist. Where did these traits come from? Jonathan Maitland finds out what makes Nick Davies tick. Producer: Arlene Gregorius.

The IMF elects the French Finance Minister, Christine Lagarde as its new Managing Director. Front-runner Ms Lagarde, who's used to breaking glass ceilings in the world of politics and economics, becomes the first female head of this international financial institution. A yoga and exercise enthusiast - she once represented France in synchronised swimming - she wears Chanel and treasures the simple pleasures of her rural retreat in Normandy. A healthy contrast perhaps to the challenges facing the International Monetary Fund in Europe as Greece struggles to manage its political crisis and the threat of default. Adrian Goldberg reports.

Bashar al-Assad of Syria is facing a serious challenge to his rule in the form of widespread political protest across the country. Simon Cox examines how instead of training to be an eye doctor in London he was thrust into the role of leader of an Arab state in the of a political storm. Had his brother not died, Bashar would almost certainly have been destined for a quiet life outside politics and far from the spotlight. He came to power in 2000 on a wave of hope for political and economic reform. Under his leadership, the country underwent a degree of relaxation, with hundreds of political prisoners being released and a few tentative steps towards easing media restrictions. But the pace of change has slowed - if not reversed - and President Assad has made clear his priority is economic rather than political reform. The Syrian leader's vocal opposition to the US-led invasion of Iraq prompted US anger, but it was popular in Syria and in the region. His administration has also come under fire for its alleged support for Palestinian militants and insurgents in Iraq. For Syria's security services and army, the ruling Baath Party and the massive state bureaucracies, Mr Assad represents stability and continuity after the 30-year rule of his father, Hafez al-Assad. Some observers believe an old guard with entrenched interests may be holding back the young leader. Others say Mr Assad is firmly in the driving seat. So how much do we know about the real character of the man - is he reformer or autocrat? Presenter: Simon Cox Producer: Ian Muir-Cochrane.

Martin Amis has a reputation as a literary bad boy and has caused a stir in a recent interview with a French magazine talking about the 'moral decrepitude of England' and saying he would 'prefer not to be English'. It's not the first time Amis has courted controversy: he offended Muslims by saying they 'ought to suffer until they get their house in order' and earlier this year he riled children's authors by saying 'If I had a serious brain injury I might well write a children's book'. Those who've met him, however, say he can be charming and he commands the loyalty of several high profile friends.
