SP general secretary Amar Singh, who is leading the seat-sharing talks with a Congress team headed by Rahul Gandhi, also said the party would not concede seats like Rampur and Pratapgarh on which the Congress had laid claim during the recent parleys.

The seat-sharing could be on the basis of the 2004 Lok Sabha elections or the "RJD model" adopted by Lalu Prasad in Bihar, Singh told reporters in New Delhi.

As per the 2004 poll performance of Congress, it could be given a dozen seats and if the Bihar model is adopted, then only eight seats, he said noting that Lalu Prasad had given only four of the 40 seats in Bihar to Congress. UP has 80 Lok Sabha seats.

Singh said that during the talks, the SP has also sought "few" seats in other states like Maharashtra, Karnataka and Madhya Pradesh.

Expressing opposition to the Congress' idea of "friendly fights" on a few seats in UP, he said that "in such an eventuality, there will be friendly fights in 78 seats and that the SP will extend support to Sonia Gandhi and Rahul Gandhi in Rae Bareli and Amethi respectively".

Singh made it clear that his party was not ready to vacate any of the seats won by it in the last Lok Sabha elections, including Allahabad, to Congress.

Besides, he said that it was for the Congress to think how effectively it could contest seats like Ghaziabad and Varanasi amid BJP's reported plans to put up Rajnath Singh and Murli Manohar Joshi from there.

Singh gave enough hints that Raj Babbar and Beni Prasad Verma may find little sympathy during the seat-sharing. The two MPs are currently suspended from SP and have moved closer to Congress.

The SP, however, was ready to give the newly created seat of Daurhara for Union Minister Jitin Prasad whose seat Shahjanahpur is now a reserved constituency.

Asked whether efforts would be made to rope in RLD in the SP-Congress alliance, Amar Singh pointed to its chief Ajit Singh's history of choosing allies, suggesting that he could not be easily trusted.

He said that Singh went along with the BSP in the recent trust vote in Lok Sabha after ensuring that the Congress-led government renamed the Amausi airport in Lucknow after his father late Chaudhury Charan Singh and later held talks with BJP's Mukhtar Abbas Naqvi.

To a query whether he wanted removal of the AICC general secretary in-charge of UP, Digvijay Singh, from the Congress' team of negotiators, he replied in the negative.

Singh said it was the prerogative of the Congress president.
