“The ruling coalition has proven unable to generate internal consensus on key issues of public policy,” Verité Research, a Colombo think tank, said in a report last week, warning that the “moderate consensus remains deeply vulnerable.”
Mr. Sirisena, in the interview in his seaside office, where he keeps the air-conditioner off in the stifling summer heat, insisted he would not only get a Constitution adopted but also lead his country through the process of truth and reconciliation that his government committed to undertake in a United Nations resolution last year.
The United Nations estimates that as many as 40,000 people were killed in the last phase of the civil war in 2009. Families have reported more than 5,000 people missing, making Sri Lanka the country with the second-highest number of disappearances in the world, the world body said.
“I know it is a difficult task, and I decided to accept the challenge anyway,” Mr. Sirisena said, leaning back in a white upholstered chair, himself dressed, as always, in white, from his cotton lungi skirt to his white tunic top.
“And when you take up the challenge, you mustn’t face it crying, you must smile through it,” he said, his normally serious demeanor lifted into a grin.
But Mr. Sirisena, speaking quietly and slowly, gesturing for emphasis, urged patience.
“I am not a man who rushes into things,” he said. “That is my policy.”
Mr. Sirisena came to power in a revolution at the polls early last year, when a coalition with him at the helm defeated the previous president, Mahinda Rajapaksa. Revered by some for ending the country’s civil war, Mr. Rajapaksa was reviled by others because of allegations of corruption and human rights abuses.
When coalition members were deciding whom to put forward as their candidate against Mr. Rajapaksa, they chose Mr. Sirisena “because of the very simplicity of the man,” Mangala Samaraweera, Sri Lanka’s foreign minister, said in an interview.
There were “more efficient, more iconic persons who may have been also able to do that job, but none of them would have been able to win the trust and confidence of so many different layers of Sri Lanka’s constituencies, the Tamils, the Muslims,” said Mr. Samaraweera, who joined Parliament in 1989, the same year as Mr. Sirisena. “I really personally believe Sirisena never ever had any ambitions” for the top job.
Mr. Sirisena, who was health minister under Mr. Rajapaksa before defecting to join the coalition against him, had also been his party’s general secretary for 13 years. He began his political life as a communist, and still reveres Karl Marx, with a picture of him prominently displayed in his home.
M. A. Sumanthiran, a leading constitutional lawyer and member of Parliament from the Tamil National Alliance, said that when he was asked to support Mr. Sirisena’s candidacy, he knew him only as “a man of few words who smiles and shies away.”
But as a member of a committee appointed to advise Parliament on a new Constitution, Mr. Sumanthiran said, he was impressed at how Mr. Sirisena finessed a divisive question of ethnicity in the preamble to the new Constitution.
Convinced that a new Constitution must begin its life with unanimous support in Parliament, Mr. Sirisena persuaded all sides to drop the preamble and instead support a simple resolution for a Constitution to be drafted. That garnered unanimous support.
“These are little steps compared to what we expect him to do,” Mr. Sumanthiran said, but “it’s giving us confidence in his methods.”
Mr. Sirisena, in the interview, said lobbying fellow legislators was his forte, and laughed as he described his efforts in humorous detail. In April last year, he got two-thirds of the 225-member Parliament to support a constitutional amendment reducing presidential powers, as he had pledged to do if elected.
“I went to the Parliament dining hall, sat with them and asked them to take away my powers. I put my arm around their shoulders, held them by their arms and rubbed their bellies to convince them to take away my powers,” he said, speaking softly, his shoulders rising and falling in jerks as he chuckled to himself.
Mr. Sirisena steered clear of committing to a timeline, saying, “I don’t think the drafting of a country’s constitution should be rushed. If we rush the process, the extremists could exploit that situation.”
But moving slowly has risks, too.
To maintain support within their ethnic communities, the moderates needed to demonstrate progress, said Verité, the think tank, but the results they must show are divergent.
“The change in government has renewed Tamil expectations that their immediate grievances as well as historical grievances — particularly over power sharing — will be meaningfully addressed,” Verité said in its report.
But Verité said proposals for greater power sharing and accountability for rights abuses and war crimes are likely to be strongly resisted because the government had “made no concerted effort” to shift Sinhala opinion “in favor of a more equitable power-sharing arrangement.”
Making it harder, Mr. Rajapaksa retains sway over a big portion of Mr. Sirisena’s political party, and at every opportunity loudly denounces him as selling out his own people.
That appears to have persuaded the government to back away from a resolution it co-sponsored at the United Nations in September to involve foreign judges in a special court to investigate and prosecute human rights abuses.
“The president is reflecting a kind of general view amongst the public about not having foreign judges,” said Mr. Samaraweera, the foreign minister.
The Tamil population, skeptical of a process led by the central government, had insisted on the involvement of foreign judges, and this apparent backtracking has worried some.
“Sirisena’s attitude is to try to be deft instead of bold,” said Paikiasothy Saravanamuttu, executive director of the Center for Policy Alternatives, a Colombo research and advocacy group. “We’re waiting for him to play the fullest possible role.”
Mr. Samaraweera said government leaders plan a major effort to build support in the coming months. The first step would be to raise awareness among the Sinhalese about what really happened in the civil war, something they have been largely shielded from.
“The Sinhalese, once they know the truth, are a pretty compassionate bunch of people,” he said, predicting they will come to support the process.
Mr. Sirisena said he, too, remained convinced that his Sinhalese majority would support a new Constitution.
“For the Sinhalese people to live happily in this country,” he said, repeating a line he has used often in speeches, “the minority communities also must be happy.”
