The Shiromani Akali Dal and the Bahujan Samaj Party announced an alliance on Saturday for the next year's Punjab Assembly election.
Announcing the tie-up at a press conference, Akali Dal president Sukhbir Singh Badal described it as a “new day in politics of Punjab”.
"Today, is a historic day...a big turn in Punjab's politics,” he said in the presence of BSP General Secretary Satish Chandra Mishra.
The Mayawati-led BSP will fight 20 of the 117 Assembly seats in Punjab, while the rest will be contested by the Akali Dal, he said.
The Akali Dal earlier had a tie-up with the BJP and the Badal-led party walked out of the NDA over the farm laws issue last year.
