In a statement released by Downing Street on Friday, Cameron said:
"I congratulate Maithripala Sirisena on his victory in yesterday’s Presidential election.
"When I visited Sri Lanka I saw the huge potential the country has, and wish him well in taking every opportunity to help realise this potential and lead a stable, prosperous, united country. These peaceful, democratic elections are a credit to all those involved and the people of Sri Lanka.
"I welcome the fact that outgoing President Rajapaksa has accepted the democratic will of the people and committed to ensuring a smooth transfer of power. I encourage President-elect Sirisensa to support the ongoing UN Office of the High Commission for Human Rights investigation into human rights abuses so that the issues of the past can be addressed and the country can move forward to a brighter, peaceful future where all Sri Lankans can play a role."
