Information and Broadcasting Minister Hasan Mahmud on January 29 said that Bangladesh Nationalist Party (BNP) and their leaders are doing anti-state activities and hatching conspiracies against the country, reports The Daily Star. He said BNP as a political party could criticise the Government's activities but they could not engage in treasonous and anti-national activities by sending letters against the country abroad, to hire lobbyist firms for tarnishing the country's reputation and destroying its trade and export. Terming appointment of lobbyist firms a conspiracy against the country, Hasan said the government might carry out an investigation to find out where the illegal money went and who took it.
