Top BJP leaders on Saturday exuded confidence that the party will form the government in four states where it was in power, including in Uttar Pradesh, and will make impressive gains in Punjab. Addressing a joint press conference here ahead of the final phase of voting in Uttar Pradesh, BJP president JP Nadda and Union Home Minister Amit Shah said those hoping for any dilution in the party’s mandate in the state would be disappointed and it will get a massive majority. “People will give BJP a good majority in four states where it is in power,” Nadda said.
