"I hereby announce my resignation from @jkpdp as the party has failed the people of J&K on all fronts. I don't want to be a part of the lies and deception being perpetuated by the party. Hv sent a detailed letter of resignation to @MehboobaMufti. Will soon interact with the media (sic)," Ansari wrote on Twitter.

Imran also resigned from the PDP last month and joined the People's Conference (PC).
