NEW DELHI: Bihar chief minister Nitish Kumar on Wednesday lost his cool at Tejashwi Yadav, claiming that he broke the alliance with the Rashtriya Janata Dal because it “did not perform well” in government.As Tejashwi was speaking on the subject of the special intensive revision of electoral rolls, Nitish interrupted his former deputy and reminded him about the chief ministerial tenures of his parents.“When you were young, your father was chief minister for seven years, and your mother was chief minister for seven years. What was the situation then? I went with you for some time, but you were not doing the right thing, so I left you. We (JDU and BJP) have been together from the beginning, and we will stay that way,” Nitish said.“What have you done for women? What have you done for Muslims? We have worked for all sections. Do you even know? You were a child. Did anyone dare leave home in Patna after dark?” he added.This exchange came as opposition MLAs donned black shirts in protest against the Election Commission‘s exercise.Tejashwi questioned why the voter revision drive was not started right after the Lok Sabha election last year.“We are not opposing the SIR, but the process is not transparent. The Election Commission says they received complaints that people from outside have come as voters here. This drive was carried out in 2003, and it took a year to complete then,” the RJD leader said.“Between 2003 and 2025, many elections have been held. Should we then say Nitish Kumar is a fake Chief Minister? All of us who were elected came here with the support of fake voters?” he asked.The poll body’s exercise has triggered a major row in poll-bound Bihar, with the opposition alleging that the Election Commission is trying to verify voters’ citizenship under the pretext of revising voter rolls. They warn that a large section of people may lose their voting rights due to this drive.More than 52 lakh voters were not found at their registered addresses during the ongoing exercise, the Election Commission has said. This accounts for 6.62 percent of the state’s registered voters. Many of them have died, shifted permanently, enrolled as voters at multiple locations, or are untraceable.
