Expelled Janata Dal-United leader Shyam Rajak on Monday joined Rashtriya Janata Dal in presence of Tejashwi Yadav in Patna.
Rajak's entry into RJD comes a day after Bihar Chief Minister Nitish Kumar removed him from the State Industries Minister's post and also expelled him from the JD-U.
"We welcome Shyam Rajak in our party. We are pleased that Rajak ji has returned his old home, his real home. The way the JD-U is functioning, it has left no room for any representative in the state to play their part," said Yadav.
He alleged that Bihar, under the leadership of Chief Minister Nitish Kumar, has entered in a state of turmoil.
Earlier on Monday, Rajak told ANI that almost all ministers in the Bihar Cabinet are unhappy with Chief Minister Nitish Kumar and things will become clear in the coming days.
He, however, said that he was not aware of whether other leaders were going to leave the party but said that he will be joining the RJD.
"Around 99 percent of ministers in the Nitish Kumar Cabinet are unhappy, currently many of them are unable to make decisions. Things will unfold in due course of time.
"I, however, do not have any idea about who is going to leave the party. I am joining RJD, that is all I can say," Rajak said.
