Observers certified Madagascar's run-off presidential polls as free and credible on Sunday, urging bickering candidates to stay calm as counting continued after the vote.
By late Sunday, the current strongman's candidate, Hery Rajaonarimampianina, was leading with 15 percent of votes counted, though both sides accused the other of fraud and his rival, Robinson Jean Louis, demanded a publication of the results be suspended.
But international observers said they could fault little so far.
"According to the parameters and methodology of the European Union, the elections were free, credible and democratic," said EU mission chief Maria Muniz de Urquiza of Friday's vote to restore democracy to the island nation.
She cautioned though that "the process has not finished. We have to wait for counting to end and the reporting of the results," after both candidates claimed victory in an ominous reminder of similar disputes during 2001 polls.
The parliamentary and run-off presidential polls were aimed at ending economic and political stagnation on the island state after current leader Andry Rajoelina seized power from Marc Ravalomanana in an army-backed coup in 2009.
The two foes were barred from running for the presidency as the international community fears a return to violence, but proxy candidates ran instead.
Vote-rigging claims dismissed
Other commentators also judged the polls free and urged the candidates to accept the outcome.
Observers from the US-based Carter Center and the Johannesburg-based Electoral Institute for Sustainable Democracy in Africa (EISA) found "that voting and counting processes were peaceful, orderly," they said in a statement.
The polls' organisation was "relatively successful" despite several constraints, said EISA mission head Cassam Uteem, a former president of Mauritius.
"All the members of our team have confirmed that everything happened transparently, and we don't have any reason to believe that there has been rigging," he said.
The Carter Center noted a "few shortcomings", such as inconsistent use of separate voters lists for the presidential and parliamentary polls and late delivery of materials.
But it stressed "these shortcomings were not systematic and will not impact the outcome of the elections".
Turnout was low -- less than half the former French colony's 7.9 million eligible voters, according to the EU.
Mutual mud-slinging marked the long wait for the result.
"We are calling for the result publication to be halted and want to check all the ballot boxes to see if there are any pre-marked ballot papers," Jean Louis, 61, protege of ousted president Ravalomanana, told reporters.
The freemason doctor claimed victory after his teams collected "80 percent of results all over Madagascar" that he said showed he won 65 percent of the vote. On Saturday he had claimed 56 percent.
His rival, former finance minister Rajaonarimampianina, claimed a similar result in his favour.
The election commission, police and observers have so far confirmed no fraud allegations.
One observer experienced in elections in high-risk areas said of Jean Louis's claims of ballot fixing: "It's a classic case that candidates who don't get the score they hoped for claim fraud."
Rajaonarimampianina, 55, a former finance minister under Rajoelina, led with 53.63 percent of votes against Jean Louis's 46.37 precent, with 3,047 polling stations out of 20,001 reporting by the evening.
"If you want me to put it plainly, the figures show there's no doubt I've won," he told AFP in an interview.
"It's true it's not official yet, but I'm speaking of the trends and according to these trends I've won."
Insisting he had run a clean campaign, he dismissed his rival's fraud claims as "an argument of bad losers".
"We also have proof that in Robinson's camp many facts show there has been fraud, intimidation and also pressure on voters."
Final results are not expected before January 7, to be confirmed by the election court by February 18.
Friday's presidential run-off after an inconclusive first round on October 25 coincided with a vote for 151 parliamentarians.
"What needs to happen now is the two camps have to accept the result," one foreign observer told AFP Saturday.
