(AFP) - A total of 46 candidates including the incumbent president and his two predecessors are seeking to contest Madagascar's presidential polls at the end of the year, the Constitutional Court said Tuesday.

The court will now assess the candidates' eligibility and confirm by Sunday which ones will be allowed to stand in the first round of the elections.

The vote scheduled for November 7 comes after an outbreak of protests that forced President Heri Rajaonarimampianina to accept the formation of a "consensus" government tasked with organising a fresh poll.

If no candidate receives more than 50 percent in the first round, a second round of voting will be held on December 19.

Rajaonarimampianina, elected in 2013, will seek re-election as will his predecessors Andry Rajoelina, who was in power from 2009-2014, and Marc Ravalomanana, who held office from 2002 to 2009.

Opposition grandees Rajoelina and Ravalomanana were both barred from running in 2013 under a deal designed to bring stability to the impoverished Indian Ocean island.

Madagascar is a former French colony with a population of 25 million that has been beset by political instability for decades.

A standoff erupted over proposed electoral reforms that triggered mass protests and led the Constitutional Court to order a caretaker government to organise the ballot.

Demonstrators took to the capital Antananarivo's central square in April over Rajaonarimampianina's efforts to change electoral laws that opponents said were intended to favour his party.

The proposals were overturned by the courts.

But the protests morphed into a full-blown movement to oust Rajaonarimampianina. Clashes between activists and the security forces claimed two lives and left more than a dozen injured.
