Amal Alamuddin

London barrister Amal Alamuddin has become engaged to one of the world's most elusive bachelors, Hollywood A-lister George Clooney. But she is an impressive figure in her own right. As a high-flying human rights lawyer she has defended the likes of Julian Assange of Wikileaks, former Ukrainian president Yulia Tymoshenko and the former head of Libyan intelligence Abdallah Al Senussi. She has also been an adviser to Kofi Annan of the UN on Syria and to the UN tribunal on the assassination of Lebanese prime minister Rafik Hariri. Mark Coles talks to those who know her well.Produced by Rebecca Kesby and Arlene Gregorius.
