Opposition members, mainly from the Congress and the Dravida Munnetra Kazhagam (DMK), on Wednesday staged a protest in the Lok Sabha over clearance granted to a renewable energy project near the India-Pakistan border and staged a walkout after “not getting a satisfactory reply” from the government.

Asking a supplementary question during Question Hour, Manish Tewari of the Congress said national security and energy security have to go hand in hand.
