Trinamool Congress chief Mamata Banerjee reiterated here on Monday her demand that the 400 acres of land that she claims had been acquired from peasants in Singur without their consent for the setting up of the Tata Motors' car manufacturing project there should be returned to their owners. She scoffed at veteran Marxist leader Jyoti Basu's remark on Sunday that any attempt to sabotage the project would send the message to the people that the Trinamool Congress is against development. Rather than advise the Trinamool Congress, Mr. Basu should ask his party and the Left Front government to respect the people's verdict and return the land, she said. "Mr. Basu's advice is unwarranted and amounts to disrespecting the people's verdict in the recent panchayat polls there.' The Trinamool Congress won the rural bodies from the area in the panchayat elections earlier this month.
