The Lok Sabha on Monday passed the Interim Budget, amid walkout by key Opposition parties which alleged that the government had deviated from established conventions and rolled out several incentives to woo voters ahead of the general elections. Replying to the debate on the Budget, finance minister Piyush Goyal said the NDA government has done a lot to improve farmers' economic condition and refuted the criticism on the Rs 6,000 annual direct income support to them being meagre.
