Amal Alamuddin's photo was splashed across the world last month after the announcement of her engagement to George Clooney.

Soon, she could return to the front pages in a more controversial role — when she stands up in court to represent former Libyan leader Moammar Gadhafi's notorious spy chief in a case that could scupper the reputation of the International Criminal Court.
