The BSP, which had 80 MLAs in the outgoing UP Assembly, managed to win just 19 seats in the 403-member House.
Driven by the Modi wave, the BJP, along with its ally, had stormed to power in UP after 14 years, securing 325 seats, while the Samajwadi Party had won 47 seats and its ally the Congress seven seats.

Delhi Chief Minister Arvind Kejriwal too had claimed that EVMs were tampered with in Punjab to keep the Aam Aadmi Party out of power.
