New Delhi, May 18 -- In a major setback for the Arvind Kejriwal-led Aam Aadmi Party (AAP), 15 party councillors on Saturday resigned from the party's primary membership and announced the formation of a new political outfit - Indraprastha Vikas Party, citing "internal discontent" and stalled development works in the municipal corporation. The blow comes weeks after the AAP lost control over the municipal corporation, and months after it lost the Assembly elections to the Bharatiya Janata Party (BJP) after being in power with brute majority between 2015 to February 2025.

In the February state polls, Goel had contested on an AAP ticket from Adarsh Nagar but lost to the BJP. In a signed letter addressed to the AAP leadership, the councillors alleged that "negligible coordination with the councillors led to the loss of power in MCD." "We all municipal councillors were elected on the tickets of AAP in 2022 but despite coming to power in the MCD, the top leadership of the party was incapable of smoothly running the MCD...Due to not fulfilling the promises made to the people, we are resigning from the primary membership of the party," the letter, seen by HT, stated. Besides Goel, the letter bore the signatures of Usha Sharma, Ashok Pandey, Kamal Bharadwaj, and Devender Kumar, among others.
