Singur : Work at the Tata Motors small car plant here continued to suffer on Tuesday because of thin attendance of contract workers, as an indefinite sit-in by the Trinamool Congress partymen entered the third day.

"Attendance of the company officials was around 85 per cent, but only 20 per cent contractual workers turned up," a Tata Motors spokesman told PTI.

TC chief Mamata Banerjee said the agitation would not be called off unless the state government agrees to the party's demand for return of 400 acres of land to farmers who were allegedly forced to give up their property.

The busy Durgapur expressway near the Tata Motors plant remained closed because of the dharna, causing a traffic snarl.

Home Secretary Ashoke Mohan Chakraborty said police in Hooghly has been asked to talk to the TC leadership for reopening one side of the expressway.
