It all began after a letter emerged written by Sisodia to Yadav, with the former hitting out at Yadav asking that 'whether he was trying to finish Kejriwal or AAP?'
In his letter Sisodia wrote that 'Yadav was creating factional fights and was gunning for AAP chief Arvind Kejriwal.' Sisodia wrote: "Yogendra Yadav is misleading the leadership on AAP's prospects in Haryana."
"You are trying to draw Kejriwal into a fight between you and Naveen Jaihind. Kejriwal was firmly against fighting Lok Sabha election from so many seats and only wanted to focus on Delhi for few years, but went ahead on your suggestion, result is in front of us," he wrote in the letter.
With the fight out in the open, the AAP's prospects in the Delhi Assembly election could be in jeopardy. Reports suggest that Yogendra Yadav may quit the party on Friday. He earlier stepped down from all party posts including that of PAC.
