Colombo, Nov 21: Sri Lanka's former strongman Mahinda Rajapaksa on Thursday took oath as the new prime minister of the island nation after incumbent Ranil Wickremesinghe formally stepped down from his post.
Rajapaksa, the elder brother of the newly elected President Gotabaya Rajapaksa, will function as the prime minister of the caretaker cabinet until the general election in August 2020.
The 74-year-old leader, who described himself as "a rebel with a cause", earlier served as the country's president from 2005-2015, becoming South Asia's longest-serving leader. He was also prime minister for a brief period in 2018.
Gotabaya on Wednesday named Rajapaksa as the new prime minister after incumbent Wickremesinghe announced his resignation from the post following the presidential election debacle.
Gotaaya defeated Wickremesinghe's deputy Sajith Premadasa in the presidential election held on November 16.
Rajapaksa was appointed the prime minister on October 26, 2018, by the then President Maithripala Sirisena, who sacked Wickremesinghe in a controversial move that plunged the country into an unprecedented constitutional crisis.
He resigned on December 15 as two crucial Supreme Court decisions made the former strongman's efforts to cling to premiership untenable.
The apex court later unanimously declared that the dissolution of Parliament by President Sirisena was "illegal".
Rajapaksa became the country's youngest-ever parliamentarian in 1970 at the age of 24.
The two brothers -- Rajapaksa and Gotabaya -- led a decisive campaign that helped end the island nation's three-decade-long civil war against the Liberation Tigers of Tamil Eelam (LTTE).
