Who will catch the Prime Minister if they commit corruption?

At a recent event in Dhaka, Dr. Tasnim Zara said that while the Prime Minister heads the Cabinet, there is a critical question: if the Prime Minister engages in corruption, who will hold them accountable? Would it be the Anti-Corruption Commission? But who appoints the commissioners of that Commission?

They are appointed by the President on the Prime Minister’s advice. With such a system, how can accountability be ensured? It has reached a point where the police, who are supposed to catch criminals, are themselves appointed by the criminals. How can accountability exist in such a system?
 

He added that in a cricket match between Bangladesh and Sri Lanka, even if there are no neutral umpires, there is still a process of appeal. In Bangladesh, however, the system is designed differently. Many human rights violations occur, but who ensures accountability for those? How is the Human Rights Commissioner appointed? Everyone knows: the Law Minister appoints them, with the selection committee including the Law Minister and Home Minister. If these ministers violate human rights, the commissioner meant to hold them accountable is appointed by them.
 

He further explained that the seven-member selection committee includes the Law Minister, Home Minister, Cabinet Secretary, Speaker, and the head of Parliament, along with two MPs nominated by the Speaker (one from the ruling party, one from the opposition). So how can this committee ensure genuine accountability?
