Kolkata: Alleging chartered flights and special helicopters were used by VIPs to carry money for "purchasing voters", West Bengal Chief Minister Mamata Banerjee on Tuesday urged the Election Commission to stop any such attempts during the Lok Sabha poll campaign.

She also requested the poll panel to remove hoardings and posters put up by the Bharatiya Janata Party with armed force personnel's photographs, and ensure withdrawal of Narendra Modi government's advertisements still being screened in cinema halls even after the poll notification and the model code of conduct coming into effect.
