The Enforcement Directorate or ED, which investigates financial crimes, will investigate charges of money laundering against 12 leaders of Mamata Banerjee's Trinamool Congress who have already been named in a case filed by the Central Bureau of Investigation in the Narada sting operation case. The leaders of West Bengal's ruling party are accused of allegedly accepting cash as "illegal gratification" in a sting operation conducted by a Delhi-based news website, Narada News. Earlier this month the Supreme Court said the Central Bureau of Investigation will investigate the charges and criticised Ms Banerjee's effort to stop the premier investigation agency from handling the inquiry.
