Madagascar's opposition chief declares himself president

Madagascar's opposition chief emerged from two weeks in hiding to declare himself president, setting up another showdown with the country's increasingly isolated leader, who defied demands to resign.

Embattled President Marc Ravalomanana prevailed the first time the two men tangled, but now his power base has disappeared against an opposition that is promising elections within two years on this island off southeastern Africa known for its wildlife and eco-tourism, but also its widespread poverty and political unrest.
