New Delhi, July 31 - MPs of the four Left front parties Friday staged a walkout in the Lok Sabha demanding that the government announce a stimulus package for labourers who had lost their jobs due to the economic recession.

The 24 MPs of the Left parties -- Communist Party of India-Marxist, Communist Party of India, Revolutionary Socialist Party and Forward Bloc -- were aggrieved that the government had announced relief packages only for the corporate sector but not for those who lost jobs due to closure of industrial units, including those in the IT sector.

They made the assertion during discussion on a calling attention notice moved by the CPI-M and CPI wanting to know the measures initiated by the government to help those who had lost jobs.

The notice was jointly given by Gurudas Dasgupta (CPI) and Basudev Acharia and A. Sampath of the CPI-M.

The communists staged a walkout when Labour and Employment Minister Mallikarjun Kharge told the house in his reply that the 'positive effects of the three stimulus packages given by the government will benefit the employment sector also'.
