Another coalition government has taken over in Nepal, where Parliament elected former communist rebel leader Pushpa Kamal Dahal as prime minister on Wednesday. The change is unlikely to ease the political instability that has plagued this Himalayan nation for years. A look at 11 main challenges facing the tiny South Asian nation, home to the world’s tallest mountains:The new government led by Dahal is the ninth in the past 10 years. It is also the 24th government over the last 26 years. Most have been coalition governments as squabbling over who gets to be prime minister or gets key ministerial portfolios have often resulted in a collapse of partnerships.A single political party has been unable to capture a majority of seats in parliamentary elections, forcing it to form a coalition with the second biggest vote getter. The main partners in the last government were the two largest communist parties, but their failed to overcome the differences between them. The Maoists are former communist rebels who came to power after giving up armed struggle, while the Communist Party of Nepal (United Marxist Leninist) has been mainstream for decades. They are both competing for voters who believe in the communist ideology. Dahal led the communist insurgency between 1996 and 2006, while his coalition partner Sher Bahadur Deuba (leader of the Nepali Congress party) once offered a $50,000 bounty for Dahal’s head when he was prime minister.
