The appeal for support to Congress, in the form of a short televised speech, saw Gandhi launch an all-out attack on BJP saying its vision is "clouded with hatred and falsehood" and its ideology is "divisive and autocratic".
"Their vision, clouded with hatred and falsehood, their ideology - divisive and autocratic, will drive us to the ruination of our Bharatiyata and Hindustaniat," she said.
Gandhi said "we are fighting in this election for a future where power is not the preserve of a select few but exercised by the many".
Congress is fighting one of its toughest battles after being in power for ten years that has brought in anti- incumbency, forcing the party to fight with its back to the wall.
