New Delhi, Aug 26 (TIWN) After Ghulam Mabi Azad launched an attack on Rahul Gandhi and his coterie, the Congress has hit back.

"A man who has been treated with the greatest respect by the Congress leadership has betrayed it by his vicious personal attacks which reveals his true character. GNA's DNA has been Modi-fied," Congress general secretary in-charge communications Jairam Ramesh tweeted.

Speaking with reporters, the party's media department head Pawan Khera also lashed out at Azad and linked his resignation to end of his Rajya Sabha tenure.

"As soon your Rajya Sabha term got over, you got restless. You could not stay without a post even for a second," Khera said.

Azad on Friday resigned from all party positions, including its primary membership, ahead of organisational elections and accused the leadership of committing "fraud" on the party in the name of "sham" internal polls.

He also strongly criticised Rahul Gandhi in his resignation letter.
