The SP's alliance with the Bahujan Samaj Party (BSP) had cracked up after the Lok Sabha elections while the SBSP-BJP alliance also snapped during the polls.
SBSP President and former Uttar Pradesh minister Om Prakash Rajbhar had a meeting with Akhilesh Yadav a couple of days ago and the two leaders are said to have discussed the possibility of an alliance for the assembly by-polls.
According to sources in the SP, the two parties have almost decided to treat the by-elections as a 'test case' for the future alliance.
"SP represents the major OBC vote base, mainly the Yadavs, while the SBSP is a party of the Rajbhar community. We hope to get some more parties on board for the by-elections," a source said.
An SBSP leader said that this alliance would lead to a consolidation of other backward castes that have veered towards the Bharatiya Janata Party (BJP) in recent years.
"SP and SBSP leaders have realised that the BJP will pose a tough threat in the by-elections and then in the 2022 Assembly polls. The alliance could emerge as a formidable political force since SBSP wields influence in about two dozen Assembly seats having a sizeable Rajbhar population," said a SBSP leader.
The SBSP, sources said, has sought the Jalalpur (Ambedkar Nagar), Ghosi (Mau) and Balha (Bahraich) seats where by-elections are due. All three seats have a good share of Rajbhar votes and combined with Yadav and Muslim voters, the balance could tilt in favour of the party.
The SP, meanwhile, is also keen to stitch a new alliance, especially after the manner in which it was dumped by the BSP.
Also, the SP wants to boost the morale of party cadres and infuse hopes of a revival.
Assembly by-elections in Uttar Pradesh are scheduled to be held soon in Rampur, Tundla, Iglas, Gangoh, Jalalpur, Zaidpur, Balha, Lucknow Cantonment, Kanpur, Pratapgarh, Chitrakoot, Hamirpur and Agra assembly constituencies.
