Sharmishtha Mukherjee said it was time for the Congress to "come out of exalted echo chambers".
Senior Delhi Congress leader and national spokesperson of the party Sharmishtha Mukherjee alleged delay in decision making and lack of strategy and unity at the state level for the party's humiliating performance reflected in the Assembly poll results on Tuesday.
Ms Mukherjee, president of Delhi Mahila Congress, stated that it was high time that the party takes some action. She added that she too was responsible for the Congress' poor show.
The Congress is on the verge of drawing blank again in the Assembly polls as all its candidates were way far behind their AAP and BJP opponents on all the 70 seats. In the 2015 Assembly elections too, Congress failed to win any seat.
"We r again decimated in Delhi. Enuf of introspection, time 4 action now. Inordinate delay in decision making at the top, lack of strategy & unity at state level, demotivated workers, no grassroots connect-all r factors. Being part of d system, I too take my share of responsibility (sic)," Ms Mukherjee tweeted as the results came out.
She also accused the BJP of playing divisive politics while crediting Delhi Chief Minister Arvind Kejriwal for playing "smart politics" as the results showed a clean sweep by the AAP to return to power.
"BJP playing divisive politics, Kejriwal playing 'smart politics'' & what r we doing? Can we honestly say that we've done all 2 put our house in order? We r busy capturing Congress whereas other parties are capturing India. If we r 2 survive, time 2 come out of exalted echo chambers! (sic)," she said in another tweet.
The Congress contested the Delhi polls in alliance with the Rashtriya Janta Dal (RJD), fielding candidates on 66 seats and leaving four to its partner.
