Officials of West Bengal government said that normalcy would be ensured during today's general strike called by the Left in the state from 6 AM. The strike coincides with NDA's Bharat Bandh over the same issue.
West Bengal Chief Minister Mamata Banerjee had yesterday asked the Left not to go ahead with the strike.
Banerjee had said, "West Bengal would be further affected if bandhs are held. The previous Left Front government has crippled the economy. Going by the GDP rate, I can tell you that the state loses Rs 1737 crore on a bandh day. Taken together, the loss is around Rs 2000 crores."
She said that three years back her party had decided against calling bandhs.
