An unopposed former Communist leader was elected Nepal’s new prime minister Saturday, ending nearly three weeks of political uncertainty. Madhav Kumar Nepal of the Communist Party of Nepal (Unified Marxist-Leninist) was the only person to serve as a candidate for the post after he received backing from more than 20 of the 25 parties in parliament. Nepal, 56, is a former general secretary of the Communist Party, but had resigned after the party made a poor showing last year against another Communist movement.
