Speaking at the Congress Working Committee meeting here, Gandhi alleged that the message of the Congress was lost in an aggressive campaign of the Bharatiya Janata Party, which also took to polarising voters.

She thanked outgoing Prime Minister Manmohan Singh for "stewardship of the government".
She offered to resign as Congress president, but that was rejected unanimously by the Congress Working Committee.
