KOLKATA: Mamata Banerjee 's Trinamool Congress on Tuesday experienced a sweeping victory in the civic elections held on April 18 and 25. Trinamool Congress managed to retain the Kolkata Municipal Corporation (KMC) under it's control and also managed to increased it's seats in the 144-ward corporation. Of the total 91 municipalities where elections were held on April 25, Trinamool Congress is well ahead of it's opponents in 70 municipalities and is expected to win these civic bodies. CPI(M) and Congress are well ahead in five municipalities each and are likely to win those. Counting is still on and full results are expected by Tuesday night.BJP has also managed to increase it's strength in the KMC as the party is well ahead of it's rivals in seven municipal wards. In 2010, BJP had won just three seats in the KMC and this time the party is going to win seven seats, more than double than what they had won in 2010. The CPI(M) and the Left parties are winning 16 seats in the KMC against 33 which they won in 2010. The Congress is winning five seats in the KMC. Chief minister Mamata Banerjee dedicated her victory to the people of West Bengal. "We dedicate our victory to the people of our state," Mamata tweeted. Reacting to Tuesday's results, the chief minister also told reporters at Nabanna, the state administrative headquarters that "The opposition parties were not supposed to win a single seat. They have shared their victories among them."The chief minister also warned that her government will oppose actively the Left and BJP sponsored bandh in Bengal on April 30. Both the parties have called the bandh to oppose Trinamool Congress-sponsored terrorism in the civic polls and vote loot by them.Trinamool's only setback has been reported from Siliguri where the party has failed to take control over the Siliguri Municipal Corporation (SMC). Of the total 47 seats in the SMC, Trinamool Congress is well ahead in 17 seats while the Left parties are winning in 23 seats. BJP is winning 2 and Congress 4 seats in the civic body. It is clear that Trinamool would not be able to form the board in Siliguri.The opposition parties are still insisting that the entire civic elections were rigged by Trinamool Congress. It is clear that results of civic elections will give Mamata Banerjee a boost before next year's assembly elections in West Bengal.
