The former PTI stalwart said that Imran was the one behind the failure of the talks and the reversal of the process.
While talking to anchorperson Talat Hussain, Awan said it is one of the bitter realities of the talks related to the crucial polls, something that could've defused the prevailing crisis.
"It was an opportunity to end the crisis that came into being due to Khan sahib's demand for elections," she told Hussain.
"It followed the formation of a committee comprising the representatives and a dialogue that endorsed September as the election month," she said.
She added that Khan sahib was among those who had endorsed the consensus reached with PDM, but then everything changed.

"Since he did not have the go-ahead from his murshad [Bushra Bibi], it was all reversed, dialogue turned into a deadlock and the crisis intensified," Imran's former close aide maintained.
Nearly a week ago, the senior politician announced to quit PTI over its "violent and terrorist activities".
"I believe that the martyrs … their love and the country's respect are a part of our faith [and] those who disrespected martyrs attacked Pakistan’s foundation and ideology," she was quoted as saying.
Awan had also said at the time that "Imran Khan and Pakistan can't function together".
Defections in the former ruling party began in the wake of the May 9 unrest, that involved the targeting of security and government installations.
An exodus followed, as leaders from the top tier of the party announced to part ways with Imran Khan and his organisation. According to them, they can’t remain a part of a party that targets the army and compromises national interests.
