Tejashwi Yadav, who failed to dislodge the Nitish Kumar-BJP government in Bihar but managed to take his party to single-largest status with a high-voltage campaign, said today that the mandate was in his favour and he was the winner even if someone else was in the Chief Minister's chair. The opposition leader also alleged fraud in the counting of postal ballots and demanded a recount, flagging narrow margins in 20 seats. "Prime Minister Narendra Modi and Nitish Kumar used money, muscle power and trickery but could not stop this 31-year-old. They could not stop the RJD from becoming the single-largest party," Tejashwi Yadav told reporters.
