“The Trinamool will have to answer why they opposed the car factory that resulted in a total blockade of industrialisation,” said Bose, while releasing another Left Front manifesto for the civic polls.

A week ago, Bose had released a manifesto for 80 municipalities going to polls on May 30. Interestingly, the industrialisation issue was missing in that manifesto, which had been published at a time when the Front was unsure of the seat-sharing between the Trinamool and Congress.

The CPM is now looking for issues on which the Trinamool and the Congress share wide differences, said a party source, naming industrialisation and land acquisition as two such issues.

“We will promote both the issues in urban areas because we believe the Congress will then have to campaign against the Trinamool in 88 wards. Congress also does not approve of Mamata’s stand on industrialisation and land acquisition,” said a senior CPM leader.

From the manifesto, CPM looks all set to lead an aggressive campaign against the Trinamool.

“Kolkata wants development. The Opposition (read Trinamool) is proud to announce that it was a right decision to push back the small car project from Singur. The people of Kolkata will vote for which kind of development?” reads the latest manifesto.

“The decision to set up a car factory at Singur was right. Not only Singur, the Trinamool is opposing all development projects in Bengal,” Bose said, adding: “They say land cannot be acquired for the expansion of NH 34 connecting Dalkhola and Kolkata and for the expansion of Jessore road connecting Kolkata with the Bangladesh border.”
