Former Food Minister Sadhan Chandra Majumder was once known as a righteous person in the political arena of Naogaon district. In 2014, after taking charge as the general secretary of the district Awami League, his political journey changed drastically. He gradually began to dominate the party and government affairs.

But Sadhan changed after becoming MP minister. He is accused of trading political posts with relatives and loyalists and engaging in nomination trading in local government elections. As his power increased, he also got involved in the criminal activities of the district. He controlled the criminal underworld of the district by controlling the tenders of government works with cadre forces, grabbing ponds and land, extortion.

Local residents including Naogaon Awami League leaders and activists said that Sadhan was raised by the hands of late Awami League leader Abdul Jalil. In 1984, Sadhan was elected as the chairman of Hajinagar UP from his home area Niamatpur. At that time, he had no house to live in Naogaon city. Sadhan lived in Abdul Jalil's warehouse. At that time, Abdul Jalil used to take care of Naogaon's business and work in the market of his house. With the blessings of Abdul Jalil, Sadhan first became the general secretary of Hajinagar Union Awami League. He gradually became the district Awami League's publicity secretary and later the organizational secretary.

While Abdul Jalil was still alive, he became the joint general secretary of the district Awami League. After the death of Abdul Jalil in 2014, Sadhan became the General Secretary of Naogaon District Awami League. After that, there was no looking back.

Rezaul Islam, a former member of Naogaon District Awami League, said that Sadhan Babu has made a family syndicate to control everything since becoming a member of Parliament. The party's leaders and activists could not reach him. Removed me from the district committee and from the directorship of the chamber. He tortured many but no one dared to protest.

Khalekuzzaman, former senior vice-president of Niamatpur Upazila Awami League, said that under the influence of power, Sadhan Babu made his brother Mana Majumdar the joint general secretary of Upazila Awami League, younger daughter Trina Majumdar as member of district and upazila Awami League and elder daughter Kaveri Majumdar as vice-president of district women's Awami League. Sadhan Babu traded extensive nominations for various UP and upazila chairman posts in the district.

Talking to some auto rice mill owners in Rajshahi region, Sadhan himself and his brother Mana Majumder controlled everything from 2018 until the fall of the government. Traders used to stage dharna at Mana to get allocation of rice import from India. For this he had to pay a hefty commission. Mana Majumdar was the last word in internal collection of paddy and rice. In the last few years, a few mill owners and rice traders in Naogaon and Bogra, close to Sadhan, have been given exclusive import allocations. Dozens of mill owners in Bogra, Naogaon, Kushtia, Dinajpur and Chapainawabganj, close to Sadhan, have controlled the rice stock and market.
