JD(U) chief Nitish Kumar took oath as Bihar CM for the ninth time after joining hands with BJP on Jan 28.
When NDA chose then Gujarat CM Narendra Modi as PM face for 2014 Lok Sabha elections, Nitish Kumar ended ties with BJP.
In Nov 2015, Nitish joined hands with Lalu Prasad-led RJD and Congress to form a “Grand Alliance” and took oath as CM.
Several factors led Nitish to end ties with RJD, including the CBI probe against Lalu Yadav and his family in alleged land-for-job scam, and join BJP.
Nitish Kumar ended ties with BJP and returned to the 'Mahagathbandhan'. He helped create INDIA bloc to fight BJP.
Blaming INDIA bloc's inactivity in the run up to the Lok Sabha polls, Nitish once again ditched the Opposition and returned to the NDA fold.
