Senior party MP Ram Gopal Yadav said that the Samajwadi Party was bigger party than the BSP and if the Yadav community had not voted for BSP candidates, the party's tally would have been around four to five seats.
Ram Gopal Yadav said that Mayawati had been wrongly informed by her candidates that Yadavs did not vote for them.
"I went around the state during the elections and nowhere did anyone complain about this. I have seen SP workers campaigning for BSP candidates and vice versa. There it is wrong to allege that BSP did not get SP votes," he said.
Aparna Yadav, younger daughter-in-law of Mulayam Singh Yadav, said that she was "pained" to hear the statements of Mayawati.
"Jo samman nahin pacha pate, wo apmaan bhi nahin pacha pate (Those who cannot digest honour, cannot digest dishonor either)," she tweeted.
Aparna Yadav, incidentally, belongs to the Shivpal Yadav faction and has been supporting his party. She had contested and lost the 2017 Assembly elections as the Samajwadi Party candidate from the Lucknow Cantt seat.
She told reporters later that it was wrong to blame the Samajwadi Party for the poll debacle.
Samajwadi MLA Hari Om Yadav said that it was the Samajwadi Party that had suffered losses in the alliance with the BSP.
"If the SP had contested on its own, it would have got 25 seats and BSP, on its own, would have got zero seats. Mayawati should actually be grateful to SP cadres for winning 10 seats," he told reporters.
The BSP had won zero seats in 2014 while Samajwadi Party had won five seats which increased to eight seats after the bye-election victories in 2018.
Samajwadi legislators, meanwhile, said that the alliance did not percolate down to the grassroots level and therefore SP suffered losses.
"We will convey our views to the party president whenever he convenes a meeting. We supported BSP putting aside past hostilities but we have emerged as a loser," said a legislator from central Uttar Pradesh.
