NEW DELHI: The Aam Aadmi Party (AAP) had approached social activist Nikhil Dey in a last ditch effort to secure Congress support to form government in the Capital late last year, ET learnt on Wednesday. Sources said Dey, who works with well-known activist Aruna Roy for Mazdoor Kisan Shakti Sangathan, was approached by a top AAP leader about two weeks ahead of the dissolution of Delhi assembly in November last year.Confirming to ET, Dey said, “Someone did approach to make contact with the Congress but I did not take it further because I have nothing to do with either AAP or Congress. I do not want to identify who this person was.” AAP spokesperson Deepak Bajpai was unavailable for comment.The party’s alleged attempts at reaching out to Congress after the Lok Sabha polls has been cited as one of the reasons for a widening rift in the party leadership. AAP leader Prashant Bhushan and Yogendra Yadav reiterated this in their joint letter addressed to all volunteers on Wednesday.As per the statement, Yadav and Bhushan’s opposition to the issue of forming the government again with support from Congress led to differences with Arvind Kejriwal An AAP leader, however, defended the party. “Bhushan and Yadav were party to the decision to accept Congress support in 2013. How come what was right in 2013 suddenly became unacceptable to them in 2014? If they had such a big problem with this issue they should have disclosed this then,” the leader said. Meanwhile, ex-Cong MLA Asif Mohammed khan said he worked as mediator between AAP and Cong.
