Saif al-Islam, the prominent son of Libyan leader Moammar Gadaffi who made a rare and harsh public criticism of the country's political system in August, is leaving to work overseas, an official source told Reuters on Friday.
Islam, 36, will work in an international economic institution, the source said.
Islam's criticism, in a two-hour speech to 15,000 youth activists in the town of Sirte, were among the most critical publicly voiced by any Libyan. Islam criticized an array of alleged ills in Libyan public life, from the greed of "fat cats" in state institutions to the poor state of the health and education sectors, and called for a range of reforms.
He said the North African country lacked a free press and its political system was not as democratic as he would like.
In recent years, Islam has been seen as his father's most trusted representative.
