In Mauritania, following the recent legislative (and regional and municipal) elections in September, there has now been a change in prime minister. On 29 October, Yahya Ould Hademine (in office since August 2014) offered his resignation, which was accepted. The new nominee is Mohamed Salem Ould Bechir, who has held multiple senior government appointments, including head of the Department of Water and Sanitation (September 2013-January 2015), Minister of Petroleum, Energy, and Mines (January 2015-August 2016), and CEO of the Société nationale industrielle et minière (National Industrial and Mining Firm, SNIM, from August 2016-present). You can find a brief, official biography of him at the SNIM website, and longer journalistic biographies of him here and here.
The new PM will present his policies to the National Assembly in a month, and the deputies will then vote on his confirmation.
The Mauritanian outlet Cridem (h/t Lissnup) notes a few factors that might have gone into President Mohamed Ould Abdel Aziz’s selection of Ould Bechir. First, Ould Bechir continues a pattern where Ould Abdel Aziz has chosen prime ministers from eastern Mauritania (as this longer biography discusses, Ould Bechir is from El Aioun in al-Hodh al-Gharbi). Second, Ould Bechir may be taking on “a mission less political than technocratic” in the months remaining in the president’s term, a mission that has to do with reviving the economy (although I could, and would, argue that this is actually highly political). Third, Cridem emphasizes the close relationship of trust between the president and this “faithful servant.” Cridem closes by saying that apart from anticipating some ministerial retirements due to age and health, there is no precise sense of whom the next cabinet will include.
