Mauritanians voted yesterday in a presidential election that incumbent Mohamed Ould Ghazouani is widely expected to win with a pledge to boost investment in the West African country as it prepares to start producing natural gas.Ghazouani, 67, a former top soldier, has promised investor-friendly policies to spur a commodities boom in the country of 5 mn people, many of whom live in poverty despite its fossil fuel and minerals wealth.“The last word belongs to the Mauritanian voters. I commit myself to respecting their choice,” Ghazouani said after voting in the capital.Polls opened at 0700 GMT. Voting is expected to end at 1900 GMT, and provisional results are expected from today.Elected for a first term in 2019, Ghazouani is facing a field of six opponents, among them anti-slavery activist Biram Dah Abeid, who came second in 2019 with over 18% of the vote.Other challengers include lawyer Id Mohameden M’Bareck, economist Mohamed Lemine El Mourtaji El Wafi, and Hamadi Sidi El Mokhtar of the Tewassoul party. Casting his ballot soon after polls opened in the capital Nouakchott, 39-year-old geographer Mohamed Cheikh Hadrami said he had voted for a candidate “who will be able to reconcile Mauritanians”. He declined to say who he had voted for. Some 2mn people were registered to vote, with major election issues including fighting corruption and creating jobs for the young. If re-elected, Ghazouani has promised a natural gas-fired power plant from the Greater Tortue Ahmeyin offshore gas project, which is on track to start production by the end of the year. He has also pledged to invest in renewable energy and expand gold, uranium, and iron-ore mining.Ghazouani has presided over a period of relative stability since 2019, as Mauritania’s Sahel neighbours, including Mali, struggle with insurgencies that have led to military coups.Mauritania has not recorded a militant attack on its soil in recent years and Ghazouani, who currently chairs the African Union, has promised to manage militant threats.Prominent activist Abeid is challenging Ghazouani on his human rights record and the marginalisation of Mauritania’s Black African population, while El Mokhtar has a following among conservative and religious voters. “President Ghazouani will likely win the vote in the first round,” said Mucahid Durmaz, senior West Africa analyst at risk intelligence company Verisk Maplecroft.“The president’s re-election bid has been boosted by the ruling party’s landslide victory in legislative elections last year,” he added.If no candidate receives more than 50% of the vote, the election will go to a second round.One opposition supporter in Nouakchott, who spoke on condition of anonymity, thought Ghazouani might struggle to win outright “if the votes are conducted transparently”.In the last election, some opposition candidates questioned the credibility of the vote, sparking some small-scale protests.“Everything indicates that people want change. I will have no problem recognising the results of a transparent election, but in case of fraud we’ll not hesitate to call it a rigged election,” El Mokhtar said after voting.
