Bihar Leader of Opposition Tejashwi Yadav on Saturday slammed Chief Minister Nitish Kumar for forming four governments in as many years, saying he played with people's mandate."Four governments in four years can't be a mistake... It's playing with the mandate of the people of Bihar," said Tejashwi -- a RJD leader and former Deputy Chief Minister -- taunting Nitish Kumar without taking his name.Every time he played with the people's mandate, he called it an achivement, the Rashtriya Janata Dal (RJD) leader told the media.According to him, Nitish Kumar dumped the Bharatiya Janata Party (BJP) in 2013 and formed the government with the support of the RJD and the Congress. After that, in 2014, Nitish Kumar resigned following a humiliating defeat of his party Janata Dal-United (JD-U) in the Lok Sabha elections, and appointed a Dalit leader Jitan Ram Manjhi as the Chief Minister. But again Nitish Kumar replaced him and became the Chief Minister.Later in 2015, Nitish Kumar formed the Grand Alliance government with the support of the RJD and the Congress and defeated the BJP. He led the government for 18 months and in 2017 dumped the RJD and the Congress and joined hands with the BJP and formed government once again."Nitish Kumar has never formed a government on his own. He always became Chief Minister with the support of others," he said.Earlier, Tejashwi said: "From June 16, 2013, to date, Bihar has had four governments. In the formation and dissolution of governments, the people of Bihar lost time and development. Officials got confused. The changes of governments took place because of one individual who wanted to build his image. The people want to know who was responsible."
