Jailed former Bihar Chief Minister and Rashtriya Janata Dal chief Lalu Prasad has stopped taking lunch and is keeping quiet most of the time after his party suffered a humiliating rout in the Lok Sabha election in Bihar.The RJD failed to win any seat in Bihar, once its bastion, and in Jharkhand. Despite the Modi wave in 2014, the RJD had won four seats from Bihar.“Lalu Prasad’s routine has changed in the last two to three days. He is having breakfast and dinner but not taking lunch,” said Umesh Prasad, the doctor in-charge of the former leader at the Rajendra Institute of Medical Science here.Insulin doseAccording to doctors, Mr. Prasad, currently serving a 14-year sentence in Jharkhand in the multi-million rupee fodder scam, is given insulin doses three times a day.But since he was not taking his meals on time, the doctors were not being able to administer the doses as they did earlier. The RJD leader has also been keeping quiet most of the time, according to doctors.Zero seatsThe Bharatiya Janata Party-led National Democratic Alliance swept Bihar, bagging 39 of the 40 seats, decimating the Mahagathbandhan parties: the RJD, the HAM, the VIP and the RLSP. The Congress won one seat. This will be the first time the RJD will not have a single member in the Lok Sabha.
