The special electoral court today rejected allegations of vote-rigging and recount demands by rival Robinson Jean Louis, a former minister of public health and sports who lost in a second round of voting on the Indian Ocean island on December 20.
Rajaonarimampianina, an ex-finance minister, was backed by former leader Andry Rajoelina. Robinson was supported by Marc Ravalomanana, a leader ousted by Rajoelina in a 2009 coup.
International sanctions were imposed after the coup, and Madagascar hopes they will be lifted now that a new election has taken place.
