COLOMBO, Sri Lanka (AP) — Sri Lanka’s former President Mahinda Rajapaksa was sworn in as the prime minister for the fourth time Sunday after his party secured a landslide victory in parliamentary elections that cemented his family’s hold on power.

Rajapaksa took oath before his younger brother, President Gotabaya Rajapaksa, at a prominent Buddhist temple on the outskirts of the capital Colombo.

Mahinda Rajapaksa served as the island nation’s president from 2005 to 2015 and is highly popular among the ethnic majority Sinhalese for ending the country’s 25-year civil war against Tamil rebels in 2009.

He was first elected prime minister in 2004 and again appointed for brief periods in 2018 and 2019.

Sri Lanka People’s Front — the party led by the Rajapaksa brothers — won 145 seats in the 225-member Parliament in the election last Wednesday. Its main opponent obtained only 54 seats. A party representing ethnic minority Tamils won 10 seats, and 16 others were split among 12 small parties.

The victory gave the Rajapaksa brothers nearly the two-third majority of seats required to make constitutional changes that could strengthen dynastic rule in the country.

This time, five members of the Rajapaksa family have been elected as lawmakers– Rajapaksa, his son Namal, the eldest brother Chamal and his son Sashindra, and a nephew, Nipuna Ranawaka.
