UN employees were preparing to make an historic vote of no confidence in scandal-plagued Secretary General Kofi Annan, the online iafrica.com edition reported, quoted by AFP. The UN staff union, in what officials said was the first vote of its kind in the more than 50-year history of the United Nations, was set to approve a resolution withdrawing its support for the embattled Annan and UN management. Annan has been in the line of fire over a high-profile series of scandals including controversy about a UN aid programme that investigators say allowed deposed Iraqi dictator Saddam Hussein to embezzle billions of dollars.
