Sri Lanka’s Rajapaksa clan on Thursday tightened its grip on political power with President Gotabhaya Rajapaksa swearing-in his elder brother Mahinda as the prime minister, amidst apprehensions among the minority Tamils and Muslims on the new government’s policies.

Mahinda Rajapaksa assumed duty in his new capacity on Thursday itself. The 74-year-old leader will function as the Prime Minister of the caretaker cabinet until the general election in August 2020.

“I’m honoured to have taken oaths as Sri Lanka’s new Prime Minister. I look forward to serving all Sri Lankans as we take our country forward with a new vision to further develop and protect it for future generations,” the new Prime Minister tweeted, reaching out to all Sri Lankans.

He took the oath at the Presidential Secretariat, three days after Gotabhaya Rajapaksa was sworn in as President. Former Prime Minister Ranil Wickremesinghe, former President Maithripala Sirisena and other leaders were present on the occasion.

“I wish to congratulate and extend my warmest wishes to Hon Mahinda Rajapaksa, Prime Minister of the Democratic, Socialist Republic of Sri Lanka,” President Gotabhaya Rajapaksa tweeted.

This is Mahinda Rajapaksa’s second innings as the Prime Minister. He was Premier for a brief period in 2018 amidst a major political turmoil in the country.

Earlier in the day, Wickremesignhe formally tendered his resignation to President Gotabhaya Rajapaksa.

Wickremesignhe announced his resignation on Wednesday following the United National Party’s defeat in the presidential election.

Gotabhaya Rajapaksa defeated the UNP’s deputy leader Sajith Premadasa in the election held on November 16.

Soon after he was sworn in as the President on Monday, Gotabhaya thanked the powerful Buddhist clergy for backing his presidential bid and vowed to protect all communities, while giving foremost priority to Buddhism. He also thanked the Sinhala-majority people for electing him.

“I knew I would win the presidency with support coming only from the Sinhala majority. I told the minorities to join me. I did not receive their support. But I will make sure that I will be President for everyone,” he said.

Muslims make up nearly 10 per cent of Sri Lanka’s over 21 million people, who are predominantly Sinhalese Buddhists. About 12 per cent of the population are Hindus, mostly from the ethnic Tamil minority. Some seven per cent of the population are Christians.

There are already concerns in the country that Gotabhaya’s remarks may have led to apprehensions among the minority communities, who are already worried about the possibility of the return of an iron-fist rule under the Rajapaksa-duo’s regime.

Mahinda Rajapaksa’s attempt to win an unprecedented third term — after changing the Constitution to allow such a bid — had failed previously.

The Prime Minister, who describes himself as “a rebel with a cause”, earlier served as the country’s President from 2005-2015, a period which was mired by allegations of human rights abuses, especially against the Tamils.

Mahinda was appointed as Prime Minister on October 26, 2018.
