"This deal was done through one-to-one negotiations and private correspondence", alleged Singh.
In 2002, Sharad Pawar's daughter Supriya Sule and her husband Sadanand Sule had 20.81 per cent share holding in the company carrying out Lavasa project, said Singh.
"I had shared 80 per cent of my documents with Arvind Kejriwal but he deliberately concealed this in yesterday's press conference in which he had targeted Nitin Gdkari", said the former IPS officer.
"I had also shared the legal notes with Kejriwal. I don't know why he did not reveal, but what I feel is, in the forthcoming Delhi Assembly elections, since both Congress and BJP are major parties, Kejriwal wanted to create political space for his party, and therefore concealed the Lavasa scam", said Singh.
In 2009, Medha Patkar had set up an inquiry panel consisting of Y P Singh, Arvind Kejriwal and two others, who went through the entire Lavasa scam, said Singh. Kejriwal was fully involved in this inquiry, he added.
