The Congress told Lt. Governor Najeeb Jung Friday that it was ready to "unconditionally" support an Aam Aadmi Party (AAP) government to end a political logjam in Delhi.
A Congress source told IANS that all eight legislators of the party were ready to back the AAP, which has been invited by Jung Saturday to explore the possibility of forming a government.
The letter to Jung read: "Indian National Congress is willing to offer unconditional outside support to AAP if they are ready to form the government."
"We have come to know through media that after the refusal of BJP to form government in absence of adequate number, you have invited Arvind Kejriwal of AAP to form government," it added.
The letter was signed by party general secretary Shakeel Ahmed and Delhi Congress chief J.P. Agarwal.
All the eight Congress legislators Thursday met party vice president Rahul Gandhi and expressed their desire to support AAP.
The AAP finished with 28 seats in the 70-member assembly, just behind the Bharatiya Janata Party's 31, leaving Delhi with a hung house. The BJP Thursday said it will not form a government.
