ANTANANARIVO - Madagascar's incumbent President Andry Rajoelina has cemented his lead in an election marked by low turnout and an opposition boycott, and appeared poised to secure a third term on Monday, with over a third of voting centres reporting results.

Rajoelina, a 49-year-old entrepreneur and former DJ who first rose to power on the Indian Ocean island in a 2009 coup, had garnered 62.9% of the vote by late on Sunday, from a turnout of just 43.1%, preliminary results shared by the election commission showed.

Opposition protesters clashed with police on several occasions in the run-up to the poll, saying Rajoelina should not have run because he acquired French nationality in 2014 - which they say automatically revokes his Malagasy one - and had created unfair election conditions.

Leading opposition figures, including two former presidents, declared him unfit to run and called on their supporters to abstain from voting.
