   From friends to foes to friends again. This line easily describes the relationship that is shared between Bharatiya Janata Party (BJP) and Bihar Chief Minister Nitish Kumar. The one constant in this timeline is that Nitish remained the chief minister as was his goal and intention. On July 26, 2017 Kumar resigned from his post, breaking the two year-old mahagathbandhan that was inked between Janata Dal United (JDU), Rashtriya Janata Dal (RJD) and Indian National Congress (INC). A day later, he surprised every one by taking oath as the CM again and forming his government with an old friend turned foe turned friend again, the BJP. Here is all you need to know about Nitish Kumar and Narendra Modi who are all set to work together again. Here is a timeline of Nitish Kumar's political history. (Photo: PTI)
