Frankly, I didn't know about the latest, 2006, coup in Fiji, FT - but the reasoning seems to be the same as the earlier ones. Indian Fijians have now outnumbered Melanesian Fijians and, via democracy, achieved postitions of power (voting for their own), which leads to coups, via Melanesians in the military, and the continued ill-feeling/ethnic conflict that I noticed during my visit in the 90s.
