Upbeat after dealing another blow to the Left Front government in West Bengal in less than two months after the Lok Sabha polls,Trinamool Congress chief Mamata Banerjee on Wednesday demanded the resignation of the CPM-led state government. The CPM should draw a lesson from this verdict and step down from power. Despite their terror,the people have once again supported us within one-and-a-half months of the Lok Sabha polls, Banerjee told a Bengali channel from New Delhi. Dedicating her partys victory to ma-mati-manush (mother,land and the people),she said earlier the Trinamool had only Egra municipality in its control and now it has won in 13. She said even in Asansol,where her party had lost in the Lok Sabha polls,the Trinamool-Congress alliance had done well. Party workers should be humbled by the electoral verdict,she said. She alleged that in Rajarhat municipality where the CPM won,a huge cache of arms was seized. I have requested Prime Minister Manmohan Singh to take steps to unearth illegal arms, she said.
