TUNIS — Tunisian President Kais Saied has named Najla Bouden Romdhane, a little-known university engineer who worked with the World Bank, as prime minister on Wednesday. Romdhane, Tunisia’s first woman prime minister, will take office at a moment of national crisis, with the democratic gains won in a 2011 revolution in doubt and as a major threat looms to public finances. Saied dismissed the previous prime minister, suspended parliament and assumed wide executive powers in July and has been under pressure to form a new government. He has named Romdhane under the provisions he announced last week and has asked her to quickly form a new government, the presidency said on Facebook. — Agencies
