"It is for the top leaders like the JD(U) president Sharad Yadav, former chief minister Nitish Kumar, RJD supremo Lalu Prasad and Congress president Sonia Gandhi to sit together and collectively take a decision on joining the state government," Manjhi told reporters here.
Any decision on cabinet expansion would be taken only after their stand on joining the government, he said.
Manjhi had earlier favoured the idea of the RJD and the Congress joining his government said that the leaders of three parties would take a call in this regard.
