IT'S an astute move in a game of global chess. The naming of Prakash Shah as UN secretary general KofiAnnan's personal envoy to Baghdad is seen by diplomatic sources as yet another decisive move by Annan to wrest the initiative on the Iraq issue away from the US. "Kofi Annan wanted his own man on the ground in Baghdad. He wanted someone who was skilled, but also in whom he could trust. In Prakash Shah, Kofi has found that person," observes a senior UN official.
