"It is old wine in new bottle," he added."It is not about withdrawing support for the government, but we will use our entire force to stop the privatisation of airports," Dasgupta said.CITU leader M K Pandhe informed the workers that the Prime Minister had invited their leaders for a meeting.Pandhe, who was part of the left delegation which met the Prime Minister earlier today, asked the AAI Employees Joint Forum leadership to take up the alternate modernisation proposal as the basis of their discussions.He also appealed to the employees of Indian and other airlines as well as other employees in the aviation sector to join the agitation, and asserted that the stir would go on till the privatisation process was not scrapped.
