Young and outspoken Abiy Ahmed has been sworn in on Monday as Ethiopia's prime minister, amid hopes he will be able to quell the sustained anti-government protests that have rocked Africa's second most populous nation.Abiy was elected by Ethiopia's parliament, succeeding Hailemariam Desalegn who resigned in mid-February as a result of widespread protests that have taken the lives of several hundred people, mainly in the restive Oromia and Amhara regions."This is a historic moment," said Abiy in his inaugural address to Ethiopian lawmakers. "This is high time for us to learn from our past mistakes and make up for all the wrongs done in the past . we understand there are a lots of problems that need to be solved with great urgency."Abiy apologized for the deaths of civilians in the violent protests. He said his administration will strive to solve grievances by discussion rather than by force, provide more space for opposition parties, fight corruption and focus on respect for rule of law.The new leader said he aims to open up a fresh dialogue with arch-foe Eritrea and called upon Ethiopia's diaspora to more actively take part in the country's affairs.Abiy is the first Oromo politician to become Ethiopia's prime minister since the Ethiopian People's Revolutionary Democratic Front came to power in 1991. It is hoped he will be able to bring an end to the protests that have been raging since late 2015 to press for wider political freedoms and the release of opposition figures. The Oromo people, the largest ethnic group of Ethiopia's 100 million people, have long felt marginalized both politically and economically.A former Lieutenant Colonel in the army and head of Ethiopia's Science and Technology ministry, Abiy, 42, has a reputation as an effective orator and reformer.Many welcomed the new leader."I think this is a very important step toward the overall democratization and stability of the country," said Kiya Tsegaye, a lawyer and political analyst. "But he needs the support of the people around him, especially top party officials to implement his reform measures."Prominent opposition leader Merara Gudina expressed cautious optimism over Abiy's election, saying the future of Ethiopia's peace and stability depends on the policies of the incoming leader and his party."What he aims to achieve depends on what his party allows him to do," Merara said, adding that Abiy was elected by Ethiopia's ruling party and not directly by the population through a general election. "But still it goes without saying that a change in personalities within the leadership may bring changes in terms of bringing better ideas that may ultimately lead to national reconciliation."Ethiopia's Olympic gold medalist runner, Haile Gebrselassie, said the peaceful transfer of power is a win-win situation for all Ethiopians."The new leader's election has answered many Ethiopians' questions," Haile told The Associated Press, saying that Abiy should implement his pledges without delay. "His inaugural address today has the ability to bring together not only Ethiopians, but countries in the region as well."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.
