West Bengal Chief Minister Mamata Banerjee Saturday welcomed the SP-BSP announcing an alliance in Uttar Pradesh for the 2019 Lok Sabha elections. "I welcome the alliance of the SP and the BSP for the forthcoming Lok Sabha elections," Banerjee tweeted.

The Trinamool Congress supremo, who has been a vociferous critique of the BJP, has been touring the country over the last one year trying to build an opposition alliance to take on the BJP in the upcoming Lok Sabha elections.
