B.S.P.

But on Saturday afternoon, the B.S.P., led by Kumari Mayawati, a leader of the Dalit caste, won or was leading in only 20 seats, the election commission said.

That party and the Bahujan Samaj Party, commonly known as the B.S.P., have taken turns governing Uttar Pradesh in recent decades, in each case putting together coalitions that consisted mainly of the party leader’s caste group along with Muslims.

His predecessor, Mayawati, who goes by one name, and her Bahujan Samaj Party, or B.S.P., rose to power in no small part because of her perceived toughness on crime.

Only a month after Mr. Yadav took office in April, the leader of the opposition in the state assembly, Swami Prasad Maurya, said, "People have started remembering the good days of B.S.P.'s rule of law."

“Come what may, there will be no alliance with B.S.P. and S.P.”
