Amid the row over the alleged involvement of former West Bengal Minister Partha Chatterjee in teacher recruitment scam, All India Trinamool Congress leader Saugata Roy expressed his disappointment in the Minister and said he dishonoured the party. “He (sacked WB Minister Partha Chatterjee) has embarrassed us and dishonoured our party. We want a complete probe with an appropriate punishment for him and his associates. When the party came to know about it, action was taken against him, his ministerial posts were dropped and so were his party posts,” said Saugata Roy on July 29.
