Ravalomanana was forced from office earlier in the month under pressure from the military and Andry Rajoelina, the country's new leader.

Clifford Mamba, a Swazi foreign affairs ministry official, told the Associated Press that the regional body is considering sanctions against Rajoelina.

Sadc members are also expected to suspend the Indian Ocean island from the regional grouping.

Ravalomanana is expcted to brief Sadc leaders, as they decide how to deal with Madagascar's new government.
