From 1998, Morawiecki worked for Bank Zachodni WBK from the Santander Group, where he was promoted to the position of managing director and eventually chairman.

On 11 December 2017, following prime minister Szydło's resignation, Morawiecki was nominated to succeed her by the chief staff of the Law and Justice party, which he joined in 2016.

On 27 November 2023, after the United Right had failed to secure majority in the Sejm in the 2023 Polish parliamentary election, Morawiecki became the leader of a caretaker government.

Morawiecki stated in a press interview that at the age of 12[4] he helped his father copying underground political literature and in August 1980 he plastered the streets of Wrocław with posters calling for a general strike.

Another reason for this was his sympathizing with the Hippie movement as an early teenager, a time during which he underwent an arrest due to alleged cannabis possession.

[7] In the 1980s, at the age of 12, he edited an illegal political newspaper Lower Silesia Bulletin and was active in the Independent Students' Association.

From 1998 to 2001 he was a member of the supervisory boards of the Wałbrzych Power Company, Dialog (a local telephone-service provider), and the Industrial Development Agency.

[12] From November 1998 Morawiecki worked for Bank Zachodni WBK, Santander Group, where he began his career as deputy chair of the supervisory board, and supervisor of the economic analysis bureau and the international trade department.

With her position untenable, Szydło resigned, and Morawiecki quickly won internal party approval to be nominated as her successor.

"[28] In July 2018, Morawiecki said he "will not rest" until "the whole truth" of the World War II-era massacres in Volhynia and Eastern Galicia has been explained.

At the first sitting of the Sejm of the 9th term, he resigned from the Council of Ministers (pursuant to Article 162(1) of the Constitution of the Republic of Poland), which was accepted by the President on the same day.

[40] Morawiecki said "we do not want people to suffer as a result" of EU's Green Deal, accusing the bloc's Emissions Trading System of contributing to the 2021 global energy crisis.

"[45] In February 2023, Morawiecki said that Poland would "use its own good relations" with Turkey under Erdoğan to persuade it "to the fastest possible, and preferably concurrent, accession of Finland and Sweden to NATO.

[47] In March 2023, after Xi Jinping's three-day visit to Russia, Morawiecki expressed concern about a "dangerous" China-Russian alliance.

[48] On 14 April after the visit of Emmanuel Macron to Beijing, where he met Xi Jinping and caused alarm in Washington because he spoke of France's "sovereign autonomy", Morawiecki went there and read a prepared paper to a diplomatic audience.

"[51][52] Morawiecki response to Zelensky's 2023 UN Speech Zelensky's UN Speech in 2023 surprised many members of the Polish political establishment, as the Ukrainian leader accused his Polish counterpart of complicity with Russia due to his refusal to reopen Poland's borders to imports of the agricultural products from Ukraine.

Rather than pursuing pragmatic diplomatic channels, Morawiecki and the Law and Justice Party opted for a confrontational approach, such as banning future military aid to Ukraine, which was disproportionate and populist.

Morawiecki's claim of acting in Poland's national interest lacked credibility and was seen as a cynical move to gain nationalist votes during the parliamentary election campaign, undermining liberal support for Law and Justice.

Morawiecki's hawkish response also reflected a dependence on Kaczynski's leadership and failed to convey Poland's commitment to Ukrainian aspirations and regional stability.

While attempting to assert Poland's position, Morawiecki's actions damaged the country's reputation as a reliable international actor and neglected the tradition of fostering strong alliances, particularly with allies facing adversity.

In addition to these leading figures, there are also former ministers from Donald Tusk's first governments (2007–2014), three retired Polish army generals, two lobbyists for US arms firms, the president of one of the main employers' organizations, as well as a number of PiS representatives.

[56] On 6 November, President Andrzej Duda in his message to the nation claimed that Morawiecki will be designated as prime minister.
