The Arvind Kejriwal-led party also demanded an apology from Delhi Chief Minister Sheila Dikshit "for the massive loot going on directly under her command".
Condemning the "unethical practice" of selling of Public Distribution System (PDS) grain through black market, AAP said "government's order for a departmental enquiry was an attempt to hush up the scam rather than an honest attempt to clean up the mess".
The party, in a statement, said that Delhi was the first state to implement the Food Security Act 2013 and was the biggest scheme being implemented in the country at the cost of Rs 1,25,000 crore.
"The truth, however, is that the government is demanding votes through this scheme. The PDS through which food security is sought to be implemented is mired in deep rooted and wide spread corruption involving politicians, civil servants, police and FCI officials and unscrupulous traders," it said.
AAP: PDS scam benefited ministers of ruling party
A private news channel, in a sting operation had yesterday claimed that food grains meant for distribution to BPL families in Delhi were being sold in the black market despite a stringent mechanism in place to prevent such things.
The party said that CBI was already investigating thousands of crore of PDS scam in various parts of the country under the directions of the apex court which has benefited the ministers of the ruling party.
