The Trinamool Congress on Tuesday refuted a BJP poll complaint against Chief Minister Mamata Banerjee - that she had failed to disclose five police cases against her while filing nomination papers for the crucial September 30 Bhabanipur bypoll. The party has declared that Ms Banerjee - who must win the bypoll to remain Chief Minister, after she failed to win from Nandigram in the April-May election - was only required to disclose details of cases if she is actually named in the charge sheet.
