As Chief Executive of the Financial Services Compensation Scheme, Loretta Minghella was once at the heart of the struggle to stave off an economic meltdown in this country. But she left her high-flying career in financial services because she was wanted to highlight what she sees as a far more important crisis - that of global poverty. In 2008, after the sudden death of her brother, the film maker Anthony Minghella, Loretta decided to search for a career that put her whole self, and in particular her Christian faith, at its centre. She is now the director of Christian Aid. She talks to Joan Bakewell about her spiritual journey from an Italian-Catholic upbringing on the Isle of Wight to her new home in the Church of England; what she learned from the early loss of her brother; and her vision for a fairer world economy that treats all people as equally valuable and irreplaceable.
