ANTANANARIVO (Reuters) - Madagascar's President Hery Rajaonarimampianina challenged on Wednesday an impeachment vote against him in parliament, where critics say he has dragged religion into politics and failed to deliver on his promises.

The vote by 121 of 151 members of parliament late on Tuesday must now go to the constitutional court to determine if the head of state should be sacked, a move that threatens to derail the country's rebuilding efforts after years of crisis.
