EU and SADC observers said on Sunday that Madagascar's presidential poll was free and transparent.
Madagascar's presidential election received international observers' nod of approval on Sunday, as counting progressed slowly two days after the poll to restore democracy.
Representatives of the European Union and regional bloc SADC welcomed Friday's vote, despite organisational hiccups preventing some from casting their ballots to end a four-year political and economic deadlock.
"The elections were free, transparent and credible," said the EU's head election observer Maria Muniz de Urquiza.
"Despite certain difficulties in the organisation, the vote went well," she said, presenting a preliminary report.
The EU hailed a "calm" campaign period and election day, she said, despite isolated incidents of violence.
Muniz de Urquiza however noted concern over weak voter registration levels.
"A non-negligible percentage of Malagasies are not listed on the voters' roll," she said.
"The whole of the voter potential has not been registered," she said of the 7.8-million voters out of the vast Indian Ocean island's 22-million people.
Meanwhile the Southern African Development Community (SADC) "concludes that the Madagascar elections were peaceful, calm, fair and transparent, and reflect the will of the people", according to Netumbo Nandi-Ndaitwah, the head of its observer mission.
The SADC brokered a transitional government after strongman Andry Rajoelina seized power in an army-backed coup in 2009.
Foreign aid was frozen and the nation was kicked out of continental body the African Union, while already-high poverty levels skyrocketed.
By Sunday afternoon ousted president Marc Ravalomanana's candidate Robinson Jean Louis was leading with 27%, after under 8% of the 20 000 voting stations reported results.
Hery Rajaonarimampianina, of Rajoelina's party, was second with just under 16%, suggesting an eventual run-off poll. - AFP.
