New Delhi: All India Congress Committee Delhi in-charge P.C. Chacko resigned from his post on Wednesday after the party’s poll debacle in the assembly elections.Chacko said he has resigned taking moral responsibility for the party’s performance and has sent his resignation to Congress president Sonia Gandhi.“I have resigned from my post and have sent my resignation letter to the Congress president. It is up to her to take a decision on my resignation letter,” he said.The Congress fared poorly and was routed in the Delhi Assembly polls. It did not get a single seat for the second time after the 2015 elections.The party’s vote share also declined further from 9.7% last time to 4.26% this time, its lowest ever.Earlier in the day, he received criticism for seemingly blaming former Delhi CM Sheila Dixit for the party’s decline in the national capital. “The downfall of the Congress party started in 2013 when Sheila ji was the CM. The emergence of a new party AAP took away the entire Congress vote bank. We could never get it back. It still remains with AAP,” he said.Sheila Dikshit ji was a remarkable politician & administrator. During her tenure as Chief Minister, Delhi was transformed & Congress was stronger than ever.Unfortunate to see her being blamed after her death. She dedicated her life to @INCIndia & the people of Delhi https://t.co/XwQPlHE6cw— Milind Deora मिलिंद देवरा (@milinddeora) February 12, 2020(With PTI inputs)
