Ethiopia on Wednesday was poised to welcome a young, outspoken new prime minister as many in Africa's second most populous nation hoped for an end to the most severe anti-government protests in a quarter-century.The East African nation's ruling coalition late on Tuesday named a new chairperson, 42-year-old Abiy Ahmed, and a vote to install him as prime minister is expected in the coming days in parliament, where the coalition and its regional affiliates hold all of the seats.The announcement follows months of protests that left hundreds dead and the surprise decision by outgoing Prime Minister Hailemariam Desalegn early this year to release prominent politicians, journalists and others from prison to free up political space.But tensions continued and Hailemariam later announced his intention to resign, and a new state of emergency, the second in less than two years, was imposed in one of Africa's fastest-growing economies. Earlier this week, a number of recently freed politicians and journalists were re-arrested and accused of gathering without authorities' prior knowledge.Ethiopians had eagerly awaited news of their new leader, with many hoping the development would bring calm to the nation of 100 million people. Many Ethiopians on social media at home and abroad erupted in cheers after hearing of Abiy's selection - a rare sight in the increasingly polarized political environment.Hailemariam on Wednesday urged the nation to support the ongoing reforms and "refrain from anti-peace activities and contribute your share for the ongoing democratization in the country," the state-affiliated Fana Broadcasting Corporate reported.Abiy will be the first person from Ethiopia's largest ethnic group, the Oromo, to be prime minister since the Ethiopian Peoples' Revolutionary Democratic Front came to power in 1991. The Oromo people, despite their numbers, have long felt marginalised and have played a main role in the demonstrations.KEEP UPDATED on the latest news from around the continent by subscribing to our FREE newsletter, Hello Africa.FOLLOW News24 Africa on Twitter and Facebook. People in major towns across Oromia took to the streets on Wednesday and slaughtered animals in celebration.Ethiopia's new leader is widely seen as a fresh face in the ruling coalition, which long has been dominated by the smaller but more powerful Tigray Peoples Liberation Front. Credited with co-founding the National Intelligence and Security Service, Abiy was elected last month as chair of the Oromo People Democratic Organisation, one of the ruling coalition's four core parties, paving the way for his premiership."A fair justice system works only when human rights are respected," he said during a recent meeting in Oromia."I believe that Dr. Abiy Ahmed is the answer to Ethiopia's youths' questions," Yonas Alemayehu, an activist in the restive region, told The Associated Press.This will be the third prime minister since the current ruling coalition came to power after overthrowing the Derg military regime by force. The ruling coalition on Tuesday also decided to keep Demeke Mekonnen as deputy prime minister.A Cabinet shuffle might be coming, the coalition's general secretary, Shiferaw Shigute, hinted on Wednesday.The outgoing prime minister, Hailemariam, at times had been labeled as weak and in the shadow of former strongman Meles Zenawi, who died in 2012. Others argued that he successfully continued the late leader's core policies: economic transformation and repression.In a 2016 interview with the AP, Hailemariam acknowledged that good governance was in decline in Ethiopia, a key security ally of the United States."That is the main reason why people are protesting," he said at the time. "This is really a positive sign. I have recently apologised in front of the parliament for our mismanagement and lack of responsibility that have generated these dissents. We are now taking measures to address those grievances."However, the protests have continued to this day.Yilikal Getnet, a prominent opposition figure, said the declaration of two separate states of emergency and now the change in leadership showed that the tight grip that ruling elites once had over the public was now deserting them."This change in leadership is an indication of how unstable the government is," Yilikal told the AP. "It has got nothing to do with opening up for democratisation or a peaceful transfer of power. It's time for the ruling party to admit that solving Ethiopia's current woes are beyond its capacity."
