Rajapaksa said the restoration of full executive powers was necessary to implement his agenda to make the country of 21 million economically and militarily secure
Sri Lanka's parliamentary elections handed President Gotabaya Rajapaksa and his brother an overwhelming majority, results showed on Friday, giving the family power to enact sweeping changes to the constitution of the island nation.
Rajapaksa had sought, and achieved, a two-thirds majority for his Sri Lanka Podujana Peramuna party and its allies to be able to restore full executive powers to the presidency.
The ruling group won 150 seats in the 225-member parliament, according to a tally published by the election commission from Wednesday's vote.
The two-thirds majority will see Rajapaksa's older brother and former president Mahinda Rajapaksa taking over as prime minister as the tourism-dependent nation struggles to recover from last year's deadly Islamist militant attacks and, more recently, lockdowns to control the coronavirus pandemic.
Rajapaksa said the restoration of full executive powers was necessary to implement his agenda to make the country of 21 million economically and militarily secure.
The brothers are best known for crushing the Tamil Tiger rebels fighting for a separate homeland for minority Tamils during the elder Rajapaksa's presidency in 2009, ending a 25-year civil war.
"We will ensure (Sri Lanka) will not stand disappointed during our tenure," Mahinda Rajapaksa said on Twitter.
Currently, significant power is bestowed on parliament and the prime minister after a previous government led by the opposition had amended the constitution and set up independent commissions to oversee the police and the judiciary among other arms of the government.
"We have seen in the past when governments have had a two-thirds majority it does not have to worry about checks and balances," said historian and political scientist Jayadeva Uyangoda.
"In fact, they have untrammeled power, that is what we have observed in both India and Sri Lanka. In the past in Sri Lanka the governments which had this level of power in 1970 and thereafter in 1977 generated a lot of social discontent."
Sri Lanka's economy contracted by 1.6% in the first quarter of 2020, as Covid-19 restrictions battered the country still recovering from last year's Easter Sunday bomb attacks that killed 269 people and paralyzed the tourism industry.
On a congratulatory phone call from Prime Minister Narendra Modi of India, which is keen to check Chinese influence on its southern neighbor, Mahinda Rajapaksa vowed to deepen ties between the two countries.
"With the strong support of the people of Sri Lanka, I look forward to working with you closely to further enhance the long-standing cooperation between our two countries," he told Modi. "Sri Lanka and India are friends and relations."
