The Bharatiya Janata Party-led National Democratic Alliance on Wednesday staged a walkout in the Lok Sabha during the Zero Hour seeking prime minister's response to a Supreme Court judge's statement that he was "approached" to change a judge in the fodder scam.

The walkout came after BJP leader V K Malhotra demanded that Prime Minister Manmohan Singh [Images] respond to Justice S N Variava's statement that "someone" called him seeking to get the trial judge in the fodder scam case changed.

Railway Minister Lalu Prasad Yadav is one of the main accused in the fodder scam.
