The Congress will respond to a letter sent by the Aam Aadmi Party in "a day or two", a party official said Saturday.
Congress general secretary Shakeel Ahmed told the news agency: "(Congress president) Sonia Gandhi has marked Arvind Kejriwal's letter to me and we will frame a reply and respond to it in a day or two."
AAP leader Kejriwal on Saturday said they have sent letters to Gandhi and BJP president Rajnath Singh, seeking to know their stand on 18 issues regarding Delhi.
Kejriwal met Lt Governor Najeeb Jung and sought 10 days time from him for responding on the offer to form the government.
