Awami League Presidium member Mohammad Nasim on Wednesday said the connection between BNP Chairperson Begum Khaleda Zia`s London visit and killing of foreigners should be investigated, reports BSS."Earlier, whenever she (BNP Chairperson) visited abroad something bad happened in the country. BNP resorts to conspiracy whenever the country achieves any award...So it must be investigated that whether there is any connection between Khaleda`s London visit and killing of foreigners here," he said.He was speaking as the chief guest at a discussion marking the 39th founding anniversary of Gano Azadi League at National Press Club auditorium.Nasim, also the health and Family Welfare Minister said, "The stand of Jamaat-e-Islami is clear. BNP speaks for Liberation War but in reality they practice politics with Jamaat...they become isolated from people for their dualism.""They will not gain anything from making plots because the country will go forward under the leadership of Prime Minister Sheikh Hasina foiling all kinds of conspiracies," he added.
