Chennai: The DMK-Congress alliance is heading for a split as six Union Ministers of the regional party are set to resign on Monday even as Finance Minister Pranab Mukherjee appealed to Tamil Nadu Chief Minister M Karunanidhi to reconsider his decision to pull out of the UPA Government.

DMK Parliamentary Party leader T R Baalu said that Mukherjee called him to convey to Karunanidhi that he and the party should review the decision to pull out of the government.

Baalu told Mukherjee that the decision was taken by the party's high-powered committee after deep thinking and considering all factors. He also told the Congress Party leader that his views would be conveyed to the DMK Party chief.

However, DMK sources said there appeared to be little likelihood of reconciliation.

Six DMK ministers will meet the Prime Minister in Delhi and hand over their resignation. 

Congress General Secretary Ghulam Nabi Azad, in-charge of party affairs in Tamil Nadu, met Mukherjee and discussed the situation in the state.

The two leaders will meet Congress President Sonia Gandhi and Prime Minister Manmohan Singh and brief them about the situation in Tamil Nadu.

After seat-sharing talks between the two parties collapsed, the DMK announced on Saturday its decision to withdraw its ministers from the Manmohan Singh cabinet.

To a question, Karunanidhi had said the Congress' demand for 63 seats over the agreed number of 60 was one of the reasons for the DMK's decision.

Union Chemicals Minister and Karunanidhi's son M K Alagiri had said in Chennai that his party did not expect the Congress party to "come back" for a possible patch up.

"I am happy," Alagiri said when asked about DMK's decision to pull out of the UPA cabinet of which he is a part. He claimed Congress' exit from the alliance would not have any impact on DMK's poll prospects.
