Wojciech Król, a Polish lawmaker and senior Civic Platform figure, is facing four corruption charges in a European Public Prosecutor’s Office investigation tied to tram infrastructure modernization in the Upper Silesia-Zagłębie Metropolis, escalating a case that is now putting pressure on the ruling camp’s anti-corruption credentials.
Polish lawmaker Król faces corruption charges

The case matters beyond one politician because it links alleged bribery to public infrastructure spending, an area that draws EU and municipal funds and is central to investment and local transport modernization. Prosecutors say the alleged benefits included a trip to Thailand and access to a car for a foreign trip, while Król denies wrongdoing and says the allegations do not relate to the Silesian tram issue.
His detention only became possible after parliament on Wednesday approved his arrest, underscoring how politically sensitive the case has become. Król was then detained in Warsaw and taken to Katowice, with his lawyer saying the charges are corruption-related but disputing the prosecution’s interpretation of the facts.
The lawmaker, in parliament since 2015, has already been suspended from the Civic Platform parliamentary club and lost his post as deputy caucus leader. He also serves as chair of the National Media Council, which broadens the political fallout for Prime Minister Donald Tusk’s bloc at a time when it is already facing pressure over governance and security.
For investors and businesses, the key issue is whether the probe spreads to other officials or contractors involved in regional infrastructure projects, potentially delaying tenders and raising scrutiny around public procurement. That could matter for firms exposed to Polish local-government capex and EU-backed transport projects, where compliance risk can quickly turn into funding and execution risk.
The next catalyst is whether prosecutors broaden the case or file further charges as the investigation advances in Katowice.
