New Delhi: As the government maintained on Saturday it is yet to take a decision on Prime Minister Manmohan Singh's participation at the upcoming Commonwealth summit in Colombo, a new and disturbing Channel 4 video on the alleged arrest, sexual assault and killing of a pro-LTTE Sri Lankan news reader is causing concern. Union Finance Minister P Chidambaram on Saturday met DMK chief M Karunanidhi in Chennai. Speaking to reporters later, he said a decision is yet to be taken on the prime minister attending the Commonwealth Heads of Government Meeting (CHOGM) in Colombo November 15-17.

The finance minister termed reports of Manmohan Singh's likely participation in CHOGM as incorrect. Chidambaram also condemned the alleged rape and murder of Sri Lankan woman Isaipriya and urged the Sri Lanka government to take action against those who are responsible for it. In New Delhi, Communist Party of India (CPI) leader D Raja also said that India should boycott the CHOGM meeting in the light of the Channel 4 video which he termed as another evidence of human rights violations and war crimes by Sri Lanka.

With Tamil parties demanding that India boycott CHOGM, the Channel 4 video, to be broadcast on Sunday night on the channel, would act as added incentive to them to raise the decibel level against the prime minister's participation, it is learnt. Canada, which has a sizeable Sri Lankan Tamil diaspora, is boycotting the Commonwealth summit over the alleged human rights violations and war crimes. It is the second largest contributor to the Commonwealth fund. The new chief minister of Sri Lanka's Tamil-majority Northern Province CV Wigneswaran has invited Manmohan Singh to visit Jaffna, the capital of the Tamil majority province. Sri Lanka held elections to the Northern province for the first time last month in which the Tamil National Alliance emerged victorious.
