Opposing the Centre's decision to disinvest 10 per cent of its equity in Neyveli Lignite Corporation, DMK on Thursday threatened to pull out of the UPA government.
"When the Centre is unable to accept the NLC workers demand, we are considering whether we should continue in the UPA government and accept responsibility for the decision," DMK President and Tamil Nadu Chief Minister M Karunanidhi said.
"I have asked the DMK ministers to inform this to the prime minister," he said.
DMK, which has 16 MPs, heads the Democratic Progressive Alliance in Tamil Nadu. PMK, the other constituent, has six MPs. Congress is also part of the DPA in Tamil Nadu.
