Chandrika Rai, the father-in-law of Tej Pratap Yadav and two other Rashtriya Janata Dal (RJD) MLAs —Jai Vardhan Yadav and Faraz Fatmi, joined the Janata Dal (United) on Thursday. Rai had served as transport minister in the RJD-led Mahagathbandhan government in Bihar. Rai's ties with Lalu Prasad Yadav's family strained after Tej Pratap sought a divorce from his daughter Aishwarya.
