Punjab Congress president Amarinder Singh, who steered the party's campaign for the assembly elections in the state, accepted the responsibility for its defeat and offered to resign from his post.
Capt Amarinder, who was also announced as party's chief ministerial candidate by AICC general secretary Rahul Gandhi, said that he was ready to resign from his post if the party high command wanted him to do so.
Talking to reporters here, he said that the Congress would go into analysis of the reasons for its defeat but added that the rebel factor must have played a big role in the party's defeat.
However, he said the party had slightly improved its performance as compared to the 2007 assembly elections. The Congress won 46 of the 117 assembly seats in the state as compared to 44 in the previous elections.
He said that the Congress would play the role of a constructive opposition in the state assembly.
