Sanjay Singh, the Punjab in-charge of the Aam Aadmi Party (AAP), offered to resign from his post on 27 April, a day after the party's defeat in the MCD polls.
Singh is the latest AAP leader to tender his resignation since the party was defeated by the BJP in the Delhi civic elections.
Alka Lamba, the Chandni Chowk MLA of the party resigned on 26 April. She tweeted that she was responsible for the crushing defeat the party
saw in the three wards of her constituency.
The party's Delhi convener Dilip Pandey also offered his resignation on Wednesday.
AAP MP from Punjab Bhagwant Mann criticised the top brass of the party, saying that the party committed a historic blunder in Punjab's electoral strategy. After the party's defeat, he said that the lawmakers were "acting like a mohalla cricket team", as NDTV reported.
