It's been a long time coming. A sticker on the cover of Jamaican born writer Victor Headley's 1992 novel 'Yardie' said "soon to be made into a major movie". A quarter of a century on, it finally has. Directed by British actor Idris Elba, the film - about violent Jamaican drug gangs operating in London in the 1980s - opens this weekend. On Profile this week, Mark Coles finds out more about the man who wrote the original story. Described by a friend, as an 'enigma wrapped in a mystery'. We hear from friends who grew up with him in Jamaica, from his daughter Sol - who was just eight when her father wrote the book. And we find out why at the height of his success he fled to Africa for ten years. And what he makes of the new movie. Producer Smita Patel Researcher Darin Graham.

In 2014, one of the oldest financial institutions in the City of London, Lloyd's, appointed its first ever female chief executive, Inga Beale. Next year, she will step down from the role.A champion for diversity in the workplace, Beale has overseen big cultural and technological changes at the insurance market - some controversial. A drinking ban for Lloyd's employees during working hours made the headlines in 2017, as did a loosening of the famously conservative dress code.She has faced other challenges during her leadership, notably Brexit and a "disastrous" 2017, which was one of the worst ever years for natural disasters globally. Big insurance pay-outs led to Lloyd's reporting a £2bn loss that year. Inga Beale, one of the UK's few openly bisexual senior business leaders, did not follow a typical route to the top. She dropped out of financial services for a year to go back-packing in Asia and Australia, and is a former competitive rugby player.

Labelled 'the rebel who forgot to rebel', who is Dominic Grieve?

Characterised as both a benevolent philanthropist and as a meddling influence, George Soros has been present at some of the most defining moments in modern history.Soros was born into a Hungarian Jewish family, and later took on a false identity to survive the Nazi occupation in 1944. It was an experience that shaped his life and his outlook and he went on to escape to the West via his knowledge of the international language Esperanto.Beginning his career as a tobacco salesman, Soros went on to fund one of the most successful hedge funds in US history. Known for his high risk and brazen approach, he is infamous for his involvement in the devaluation of the British pound, known as Black Wednesday. But his career as a financial investor was not limited to the markets - he went on to use his money to promote non-violent democratisation in Central and Eastern Europe and beyond. More recently he has proved a controversial figure, providing funding for the pro-Remain campaign in the UK Brexit debate and is now the subject of vilification by the leaders of his native Hungary.
