Accusing ministers and Prime Minister Sheikh Hasina's advisers and her family of being involved in massive corruption, BNP acting secretary general Mirza Fakhrul Islam Alamgiryesterday urged her to resign taking responsibility of the graft.

Mirza Fakhrul was addressing a demonstration organised by BNP-led 18-party alliance's Dhaka city unit in the capital's Nayapaltan protesting corruption.

He alleged that the government and Sonali Bank high-ups were involved in the recent Hall-Mark scam and demanded exemplary punishment to Hall-Mark's owners and Sonali Bank's board of directors.

"Adviser Modasser Ali and a state minister helped Hall-Mark loot money from the bank, so the prime minister can not avoid the responsibility," he said.

A Bangladesh Bank investigation found that the Ruposhi Bangla Hotel branch of Sonali Bank had lent Hallmark Group Tk 2,686.14 crore between 2010 and May this year on forged documents.

He added that the government was trying to give the perpetrators a clean slate like the one former railways minister Suranjit Sengupta was given.

AroundTk 70 lakh was found in Suranjit's personal aide's car on April 9, which later forced him to resign. Later, the ministry's internal investigation found Suranjit innocent.
