Kolkata, June 2 (IANS) Calling for immediate assembly elections in West Bengal, Trinamool Congress chief Mamata Banerjee Wednesday said the Left Front had lost its right to govern the state after being dealt a big blow by her party in the civic polls.

"We congratulate the people of Bengal. It is the victory of Bengal's Maa, Mati, Manush (mother, land and people) The state government has lost all right to be in power and assembly elections should be held immediately in West Bengal," Banerjee told mediapersons here on her arrival from Delhi.

The West Bengal assembly polls are due next year.

The Trinamool swept the Kolkata Municipal Corporation (KMC) by decimating the Left Front - which has run the board since 2005 - and also came up with an impressive showing in the municipalities of various districts.

Banerjee said the Trinamool will control more than 50 civic bodies, out of the 81 that went to polls Sunday.

As the results poured in, Trinamool candidates celebrated wildly all over Kolkata. The outcome is considered a huge blow to the Left, which had been in control of 54 of the 81 civic bodies, including KMC.

Before leaving for Kolkata, Banerjee, who is also railway minister, had said in New Delhi: "I have full faith in people. It's too early to come to any conclusion."

More than 70 percent of voters had exercised their franchise in the polls. The elections were held two days after the Gyaneshwari Express rail disaster claimed 148 lives in West Midnapore district.

The Trinamool Congress and the Congress had failed to clinch a seat-sharing deal.
