In a bid to blunt the RJD's assertion that the NDA managed to win the Bihar assembly election by getting only 12,270 votes more than the Grand Alliance led by the party, Chief Minister Nitish Kumar on Friday said that victory by even one vote is ultimately a triumph. If anyone thinks that irregularities have been committed in the election, he can move the court for the redressal of grievances, Mr Kumar said in the assembly while replying to a debate on the Motion of Thanks to the Governor's address.
