President Michel Martelly praised the “pluralism” at the centre of the new government and said it was down to the “goodwill” of the opposition.
He had been ruling by decree since last Tuesday, when parliament was dissolved.
But opposition leaders have accused the president of failing to deliver in forming a consensus government.
Haiti’s new government is headed up by Prime Minister Evans Paul, a former mayor of Port-au-Prince and an unsuccessful contender in the 2006 presidential elections when he received just 2.5% of the vote. via BBC News
