The BJP-led Centre is hatching a “big conspiracy” against AAP, its national secretary Pankaj Gupta alleged on Tuesday over a supplementary ED charge sheet naming the party in the alleged excise policy scam.

Gupta also accused the BJP of wanting to finish off AAP, which governs Punjab and Delhi, at any cost. A city court on Tuesday took cognisance of the seventh supplementary charge sheet filed by the Enforcement Directorate (ED) in the money-laundering case linked to the alleged excise policy “scam”.
