Bharatiya Janata Party's (BJP) Bihar President Nityanand Rai says that the National Democratic Alliance (NDA) will make a clean sweep of all the 40 Lok Sabha seats in the state in the 2019 general elections.

"The BJP has devised a strategy with its allies to ensure NDA's victory in all 40 seats. The opposition is weakening day by day in Bihar with prime opposition face Lalu Yadav in jail and his sons mired in a family feud," Rai, a Lok Sabha member from Ujiarpur, told IANS.
