"Delhi defeat was shocking for the Congress team," said the party's Rajya Sabha member Ambika Soni, who was in the city for the annual day of Delhi Public School.
Although she refrained from naming any prime ministerial (PM) candidate, she said the observers were taking feedback on all candidates selected.
In city on Saturday, the former minister said, "The Delhi defeat was definitely shocking and the party was taken by surprise, but yes there will be some strategy that will be followed."
She added that the process for selecting the prime ministerial candidate had started in the party and the name would be announced very soon.
"I do not know the name of the PM. All I want to say is that the candidate will be the best and would be more than upright in serving the country and also its needs," Soni added.
When asked about the problems being faced by the Congress due to various allegations, she said, "No I would rather not answer these questions."
