The Trinamool Congress-led alliance will oust -- with a big margin -- the Left Front which has ruled West Bengal for 34 continuous years, a Headlines Today-ORG post-poll survey predicted on Tuesday.
According to the survey, the Trinamool Congress-Congress alliance will get two-thirds majority, winning 210 to 220 seats out of a total 294 seats in the state assembly.
The survey predicts just 65 to 70 seats for the Communist Party of India-Marxist-led Left Front.
The survey gives 10 to 15 seats to independents and other parties.
The counting for the six-phased polls, which ended on Tuesday, will take place on May 13.
