- Rahul Gandhi dismisses exit poll results for UP which predict BJP win
- Congress fought UP elections in alliance with Samajwadi Party
- Exit polls predicted BJP win in Bihar in 2015, did not happen: Rahul
"Our alliance is winning. Such exit polls we saw in Bihar also. We will talk tomorrow," said Mr Gandhi, who has sole charge of the party and key decision making with his mother and Congress president Sonia Gandhi away abroad for medical treatment.
In Bihar two years ago, Chief Minister Nitish Kumar was re-elected, leading a "grand alliance" with Lalu Yadav's RJD and the Congress to a big victory. Many exit polls had predicted a BJP win, but the party came in a distant number two.
Mr Gandhi's party was the junior partner in the Bihar alliance and has played a similar role in Uttar Pradesh, where it has partnered with Chief Minister Akhilesh Yadav, who is seeking a second straight term.
Mr Gandhi has led his party from the front in this year's assembly elections, particularly in UP where he has campaigned extensively, and if the Congress fares poorly again on Saturday, questions about his leadership will be resurrected. The Congress has been on a downward slide losing state after state since its disastrous performance in the 2014 national election, when it could win only 44 Lok Sabha seats, its lowest tally ever.
Among the states where elections were held this year, the Congress currently rules Manipur and Uttarakhand and is struggling to retain them. Most exit polls showed the BJP taking both states.
