SINGUR: Hardening its posture, the Trinamool Congress ruled out any compromise with the West Bengal government or the Tata on Singur issue, threatening to intensify the agitation and take it to the doorstep of the state secretariat.

"Return 400 acres and we will leave Singur. But we will not bow our heads to the CPM and the Tatas and for that I am ready to sacrifice my life," Trinamool chief Mamata Banerjee, who is on an indefinite dharna outside the Tata Motors plant since August 24 told a gathering.

"I am still holding my patience. It is not a movement by any political party but a farmer's movement. We have already agreed that the main factory of the plant will be set up on 600 acres. How much more blood of farmers do they want?" she asked.

Commenting on the concern expressed over the obstruction of movement of trucks as traffic on Durgapur Expressway, the busiest freight corridor in the state, remained paralaysed for the fourth day today due to Trinamool Congress's dharna in Singur, Banerjee said, "The government is now holding brief for the truck operators after looking after the interests of the Tatas."

"One road has been closed. Next it is turn of Chief Minister Buddhadeb Bhattacherjee's doors to the Writer's Buildings (state secretariat) to be closed," she said.

She said instead of two-hour road blockade across the state beginning 3 pm on Friday it would be one-hour road blockade from 4 pm. "The step was taken considering the people's inconvenience in mind", she said.
