Karra, who was elected from Srinagar parliamentary constituency in 2014 on PDP ticket, also hit out at Prime Minister Narendra Modi.
Talking to reporters here, the 61-year-old MP said he has decided to disassociate himself from the primary membership of the PDP and from the membership of the Parliament.
"The decision was tough as I have invested my youth in my party. I was opposing the alliance for last 16 months and I say it with pain that I have failed," he said, adding that he was not resigning out of any "compulsion or convenience but because of conviction".
Karra alleged that Modi has pushed the country towards Hinduisation and turned "Incredible India into Intolerant India"

"The Prime Minister has pushed the country towards Hinduisation and by doing so undermined Indian nationalism which has liberal space and place for diversity built into it.
The MP, who was once tipped to head the Jammu and Kashmir government with support of Congress when political stalemate had dogged the state after the death of Mufti Mohammed Sayeed in January this year, alleged that the Central and state governments policies of "unabated genocide", continued denial of the dangerous ground realities, insensitive and adhoc approach towards Kashmir issue led to his resignation.
"My heart is bleeding and my soul is crying for the people of my homeland. My conscience cannot take it any longer," Karra said.
He said PDP was floated in 1999 to safeguard lives, property, honour, dignity, self respect and political aspirations of the people. "But today, in the present tragic circumstances, (PDP) made a U-turn and treated its subjects much worst than the Nazi forces. I feel still continuing with them would be equally subscribing to the administratively inhuman and politically unethical blunders."
"I was forcefully consistent on it so that PDP buffer character would be saved which had blood and sweat of thousands of dedicated and selfless workers in it," Karra said defending his decision to resign after 69-days of unrest in Kashmir in which nearly 80 people have been killed and thousands of others have been injured.
