Terming her party's success as "historic", she told reporters after arriving from Delhi that "the CPI(M) has lost all right to continue in power in the state. Assembly elections should be held immediately.
"It is a victory of the ma-mati-manush (mother, land and the people). They have given a verdict in favour of political change in the state. I salute the people."
In an obvious reference to her party's failed alliance with ally Congress for the Kolkata Municipal Corporation elections, Banerjee said, "In this election we had to fight against the ruling party and three to four other forces."
She said that out of the 81 municipalities across the state, her party would rule in 51, and added that this win would help her party undertake development work.
The Trinamool Congress has stormed to power in the prestigious KMC with a two-thirds majority besides registering impressive wins in other civic bodies.
