Kolkata: The relation between the Trinamool Congress and the Congress-led UPA may turn bitter in the days to come as the West Bengal Chief Minister Mamata Banerjee issued whip to her party MPs to oppose the Food Security Bill to be introduced in this winter session of the Parliament.

Expressing annoyance over the proposed bill, Mamata said, “If the Food Security Bill becomes law, the state government will not be in a position to bear the whopping cost incurred on its implementation.”

The CM is already not too pleased with the Centre over ignorance of special package to deal with the battered financial condition of the state.

Former FICCI General Secretary and WB Finance Minister Amit Mitra frequently visited Delhi for a special package but the effort went in vain.

Mamata herself came to the national capital but failed to convince the Centre for the package.

Since Mamata came to power in April this year, the United Progressive Alliance has made several initiatives which have annoyed the TMC supremo. She did not visit Bangladesh along with Prime Minister Manmohan Singh on September 6 over the Tessta river water sharing pact. She declined to release additional water to Bangladesh citing the state’s interest.

The CM also opposed the Centre’s new Land Acquisition Policy. Following which Union Rural Development Minister Jairam Ramesh had to visit Kolkata to assure Mamata that no change would be made in the state’s own Land Acquisition Bill.

Speculation was rife that the TMC was going to withdraw support from UPA over the latter’s unilateral decision to allow 51 percent Foreign Direct Investment in retail and 100 percent in single brand.

Interfering in the issue, Mamata had said, “I do not support the FDI in retail but at the same time I would like to see the UPA’s continuance at the Centre.”

PM himself called up Mamata to pacify the issue. Later, Finance Minister Pranab Mukherjee informed the CM that the FDI decision has been put on hold till consensus emerges on the issue.
