West Bengal Chief Minister Mamata Banerjee claimed on April 30 that exit polls are being manipulated by the BJP to demoralize her party workers ahead of the counting scheduled for May 4. She asserted her party, the TMC, would win over
226 seats in the Assembly elections.
In a video address, Banerjee alleged that television channels aired biased projections originating from the BJP office. According to latest analysis from the Phalodi Satta Bazar, an informal but influential betting market, the BJP is projected to secure between
150 and 152 seats, surpassing the majority mark of
148 in the
294-member Assembly. In contrast, the TMC is estimated to win
137 to 140 seats, highlighting a significant shift in momentum towards the BJP.
Earlier, projections had put the TMC ahead with expectations of winning
158 to 161 seats compared to BJP's
127 to 130 seats. This change speaks to a tightening contest, especially considering that the overall electoral turnout was approaching
92-93%, one of the highest in the state’s electoral history. The convergence of these factors suggests that West Bengal is on track for a closely contested electoral verdict.
However, not all polls aligned with this trend. Axis My India, which planned to release their exit polls, withheld the data due to a
high non-response rate, stating the need for data credibility.
