A leading figure of the Gdańsk-based Liberal Democratic Congress in the early 1990s, Bielecki served as Prime Minister of Poland for most of 1991.

"[7] Remaining outside of the state sector while also continuing underground support for Solidarity, Bielecki, along with other like-minded colleagues from the University of Gdańsk (Polish: Uniwersytet Gdański), sought to take advantage of new economic reforms instituted by the communist government in the mid-1980s.

[6] Realizing that the reform laws had large loopholes in financial and tax oversight, the situation could be taken advantage of by private consulting firms, which could advise state enterprises to avoid various regulations.

[8] Using academic and personal connections from the University of Gdańsk, Bielecki established working relationships with Polish Ocean Lines and other state enterprises.

[6] As few consultancy bodies existed in the communist People's Republic of Poland (PRL), Bielecki's academic and personal connections with sympathetic university professors and alumni were crucial in obtaining work at the time.

[11] During the splintering of the Solidarity Citizens' Movement throughout 1990, Bielecki and other Gdańsk intellectuals increasingly favoured a liberal approach to reform the Polish economy.

Appearing at the World Economic Forum (WEF) in Davos, Switzerland in February 1991, Bielecki asked Western creditor nations to forgive 80 percent of Poland's $46.6 billion foreign debt.

[14] In June, the Bielecki government proposed a massive privatization program to sell 400 state enterprises, nearly 25 percent of Poland's industrial sales output.

[14] Under Bielecki, Poland voted to dissolve Comecon (Council for Mutual Economic Assistance) and the Warsaw Pact, whose organizations officially disbanded between June and July 1991.

[17] The proposal was later changed, envisioning Poland divided into ten or twelve voivodeships (Polish states) with the central government administering policy within each region.

"[19] Despite gaining half of the Sejm to favour both proposals, Bielecki lacked the two-thirds majority needed to pass the act of either special power.

[19] With allegations of corruption from members of his government, along with a worsening economy, Bielecki and the Liberal Democratic Congress emerged from the 1991 parliamentary elections with mixed results.

In the coalition negotiations that followed, the Liberal Democratic Congress pulled out of government formation talks with the Center Civic Alliance group dominated by the Centre Agreement, due to economic and cabinet differences between both camps.

As a member of the Sejm and one of the leaders of the Liberal Democratic Congress, Bielecki continued his support for stronger political and economic integration into Europe.

"[22] During the early 1990s, Bielecki also strongly supported the Visegrád initiative with Czechoslovakia and Hungary, greater integration with NATO, and encouraged Polish political and economic policy to take inspiration from successful Asian Tiger and Latin American nations as positive examples.

[25] Deeply frustrated by economic hardships brought on by privatization, voters punished the Suchocka government in the September 1993 parliamentary election, with Bielecki's Liberal Democratic Congress losing the entirety of its seats in the Sejm.

[26] After the severe defeat, Bielecki was appointed to the board of directors of the European Bank for Reconstruction and Development (EBRD) in December, where he remained until September 2003.

The speculation began following comments made by former referee and PZPN president Michał Listkiewicz that Bielecki would be an ideal choice to head the association due to his international experience and passion for the sport.

[33] In May 2013, members of the opposition Law and Justice party alleged that a report from outgoing ABW head Krzysztof Bondaryk accused Bielecki of illegally lobbying for Russian companies in order to acquire shares of ZA Tarnów, a chemical production facility.

Bielecki has also published articles within a number of newspapers and magazines, including The Wall Street Journal, Die Welt, Rzeczpospolita and Gazeta Wyborcza.

In September 2012, tabloid newspaper Fakt photographed Bielecki arriving and leaving work at the Chancellery on a BMW F800R, dressed in jeans, a black jacket, sneakers and wearing a backpack.

[36] The tabloid noted that while Bielecki's position in the Chancellery was entitled to a free limousine for commuting to and from work, the former prime minister preferred instead to use his personal motorcycle.

[37][38] Bielecki is also known to play football during his free time against his fellow former premier and current President of the European Council Donald Tusk.
