NEW DELHI: Senior AAP leaders Yogendra Yadav and Prashant Bhushan have written a letter to party volunteers and asked them to "stay quiet and think about what has happened so far".In the letter, Yogendra Yadav has insinuated that Kejriwal was trying to strike a deal with the Congress party to form a government in Delhi after the Lok Sabha polls."We have also asked the party Lokpal to investigate the allegations made against Prashant Bhushan and me," Yogendra Yadav said.Yogendra Yadav and Prashant Bhushan's letter comes in the backdrop of allegations by AAP top brass - Manish Sisodia, Gopal Rai, Pankaj Gupta and Sanjay Singh - that the duo along with Shanti Bhushan worked for the party's defeat in the Delhi assembly elections and maligned the image of Arvind Kejriwal "The trio, especially Prashant called up volunteers from other states and told them not to campaign for the party. I will not be campaigning for the party this time. You guys also don't campaign. It is necessary for the party to lose. It is only then Arvind (Kejriwal) will get some sense."In front of Anjali Damania (AAP leader from Maharashtra), he told the same to workers of Mysore. Those funding the party were discouraged from doing so," said a joint statement by the four AAP leaders."When volunteers were sweating out to ensure party's victory, Shanti, Prashant Bhushan and Yogendra Yadav were working for party's defeat," it said.Strongly refuting the allegations, Yadav accused the party leadership of putting pressure on the members to speak out against him as well as Prashant and Shanti Bhushan.(With inputs from agencies)
