The Democratic Party, led by the former army commander, Sarath Fonseka, joined the United National Party led coalition, the United National Front (UNF) today.

The agreement came following discussions between Mr Fonseka, who was in charge of the army in 2009 when tens of thousands of Tamils are believed to have killed by the Sri Lankan military, and the current UNP leader and prime minister, Ranil Wickremesinghe.

A Memorandum of Understanding was signed between the two parties at Temple Trees on Wednesday.

India's president, Pranab Mukherjee, on Wednesday expressed his hope to strengthen ties with Colombo, as Sri Lanka prepared to mark 'Independence Day'.

"The ties of friendship between India and Sri Lanka go back centuries and have matured over time to include all areas of contemporary relevance," Mr Mukherjee was quoted by NDTVas saying to Sri Lanka's president, Maithripala Sirisena.

The Sri Lankan government has been making contradictory statements regarding the implementation of a United Nations Human Rights Council resolution on accountability, said former Sri Lankan foreign minister G. L. Peiris.

“The sixth paragraph of the resolution clearly mentions the involvement of foreign judges,” said Mr Peiris. "However, President (Maithripala Sirisena) repeatedly denies the involvement of foreign expertise in a domestic mechanism and says the government can't rush the investigation.”

Sri Lankan police have arrested a 15 year old boy over the murder of a Tamil schoolchild earlier this month, reports The Island.

Police in Sampur are currently interrogating the teenager, after body of a 6 year old Tamil boy who was reportedly raped and murdered, was found dumped in an abandoned well.

Tamil torture victims who suffered at the hands of the Sri Lankan government called on the UN Human Rights chief to ensure that an “internationalised justice process” takes place, ahead of his visit to the island this week.

In a report by UK-based charity Freedom From Torture and the survivor activist network Survivors Speak OUT, victims called on UN High Commissioner for Human Rights Zeid Ra’ad Al Hussein to “deliver a strong message to the President and Prime Minister about the need for Sri Lanka to comply with the commitments it made to the UN Human Rights Council and the consequences if it fails to do so” during his visit to the island.

Sri Lankan Prime Minister Ranil Wickremesinghe stated the Sri Lankan constitution would not permit foreign judges to sit in domestic inquiries that would deal with mass atrocities committed during the final stages of the armed conflict.

The prime minister added that though judges could “participate” in the process, they would not be allowed to sit in on any inquiries.

Speaking at the Commonwealth Parliamentary Associations Asia Regional Seminar under the theme, ‘Role of Parliament in the Promotion and Protection of Human Rights’ in Colombo on Monday, Mr Wickremesignhe said,

"If we are to permit foreign judges to sit in judgment then our Constitution has to be amended with the consent of the people at a referendum."

"We have no provision here to have foreign judges just as much as in your countries there are no provisions for foreign judges," he told the audience. 

Mr Wickremesinghe said that this "does not preclude commonwealth judges from participating in the process" but they would be unable to sit on the proceedings. He added,

"Then there will be the big question of who shall be prosecutors. That, neither the President nor I nor Parliament can decide. We like yours have the same system, the Bar jealously guards their rights and the Supreme Court decides who should be admitted. If you have passed your exams... all and good. If you are not a lawyer of your own country, the only way is to go before the Supreme Court. If you are going to change that system the Supreme Court will say it requires a referendum."

The Sri Lankan military ceremoniously declared open a new complex which was constructed for the 563 Brigade, earlier this month.
