Baldev Singh, who is the sitting AAP legislator from the Jaito Assembly seat, sent his resignation to AAP national convener Arvind Kejriwal on Wednesday.

"I am pained to forward my resignation from the primary membership of AAP because the party has completely given up its basic ideology and principles," he wrote in his resignation letter.

Earlier, citing the "dictatorial attitude" of AAP chief Arvind Kejriwal, MLA Sukhpal Singh Khaira had on January 6 resigned from the party's primary membership.

Lawyer-activist H.S. Phoolka had also recently quit from the AAP's primary membership. He had earlier resigned from the Punjab Assembly. He was the AAP legislator from the Dakha Assembly seat.
