Tej Pratap, the elder son of Rashtriya Janata Dal (RJD) chief Lalu Yadav, is campaigning against his party, urging people not to vote for his father-in-law Chandrika Rai, an RJD candidate from Bihar's Saran candidate. The legislator, who filed for divorce last year, is also canvassing for Chandra Prakash Yadav, a candidate he has fielded from Jehanabad against his own party.
