Centre has hinted at a possible vote against Sri Lanka at a session of the United Nations Human Rights Council (UNHRC) on 21st of this month. Addressing a budget explanatory public meeting in his home town, Karaikudi, Finance Minister P Chidambaram said, if the UN resolution sought credible independent international probe, India will support it.The minister also sought to assure students demanding affirmative action against Colombo at the UN session.

Meanwhile,union ministers P Chidambaram,A K Antony and Ghulam Nabi Azad are reaching Chennai to consult DMK Chief M Karunanidhi who had threatened that his party will pull out of the ruling UPA alliance if it failed to move amendments to the US-sponsored resolution on the Sri Lankan Tamil issue at the UNHRC.Congress sources said in New Delhi that the three leaders have been asked to convince Karunanidhi that Government will not compromise the interests of the Sri Lankan Tamils at any cost.

In Lucknow yesterday, External Affairs Minister Salman Khurshid said the decision on the vote in UNHRC will be taken after consulting the southern ally of the UPA, DMK and other allies.

Close on the heels of his Friday's warning of pulling out DMK ministers from the Government, DMK chief Karunanidhi shot off letters to Prime Minister Manmohan Singh and Congress chief Sonia Gandhi, saying he feels let down by the lukewarm response of the government.

Union Minister V Narayanasamy said the Prime Minister will definitely consider all aspects before taking a decision on the resolution.

The US-sponsored motion puts the island nation in the dock over alleged war crimes and rights violations against Tamil civilians during the final phase of the war against the Liberation Tigers of Tamil Eelam (LTTE).The resolution is moved by the US for the second time. Last year, India had supported a similar resolution .
