About 3,500 people are expected to attend the ceremony, among them Polish President Andrzej Duda and EU President Donald Tusk, who was a good friend of the mayor. Duda has also declared a national mourning day.
Adamowicz, who has been mayor of Gdansk for 20 years, was stabbed in the heart and stomach during a Sunday charity event.
A 27-year-old man was arrested on the spot. The man has sentenced a jail sentence to a bank robber he claims not to have committed and blames the former government party for the Citizen Platform (PO). The mayor of Gdansk previously belonged to this party.
An increasing number of Poles believe the killer is not the only one who is responsible for the case, but also the occurrence of networking and polarization between different political parties in the country.
Politicians from the PO and the right-wing government party PiS have for many years conducted a hostile rhetoric against each other, which their respective supporters have also done. Polish media have compared the murder of Adamowicz with the murder of Poland’s then-president Gabriel Narutowicz in 1992, who was killed by a fanatic nationalist for some time Poland was hit by rampant hatred.
