[JURIST] In an apparent effort to address growing concerns about scandal and corruption in the United Nations system UN Secretary-General Kofi Annan Monday announced the appointment of UN Development Program head Mark Malloch Brown as his new Chief of Staff, the number three position in the UN structure after Annan and Canadian Deputy Under-Secretary Louise Frechette. The outspoken Brown, a Briton, a former journalist with the Economist magazine and former World Bank official, takes over from Iqbal Riza, 70. He made it clear in a morning press conference that he would be spearheading Annan's institutional reform agenda and would pursue a more public strategy in articulating UN positions on a wide range of issues.
