Tyrant's son who chose family loyalty over reform
Saif Al-Islam Gaddafi was his father's favourite son. Until the start of the Libyan revolution, he was also feted by the West as the arch-moderniser who would supposedly guide the oil- and gas-rich north African country along the path of democracy.
He was influential in his father's decision to give up weapons of mass destruction that brought Libya in from the cold in 2004 and helped to negotiate the release of the Lockerbie bomber from a Scottish jail in 2009.
Saif's extensive contacts included the Duke of York, Tony Blair and Lord Mandelson.
