North 24 Parganas (West Bengal): West Bengal Chief Minister Mamata Banerjee on Friday alleged that BJP leaders with Z and Y-plus security cover were involved in mobilising money to influence voters in the Lok Sabha elections.

"Why should so much money be spent on elections? How is so much money being circulated through Hawala? Yesterday, one BJP candidate was caught with crores of rupees. Even today, BJP leaders with Z-plus, Y-plus security cover are bringing boxes filled with money," Banerjee said at a rally here.
