The Democratic Party and the left-wing Green Alliance have presented a complaint to the prosecutor's office on the Strait Bridge. The leaders Elly Schlein (Pd), Angelo Bonelli (Greens) and Nicola Fratoianni (SI) made this known at a press conference.

Among the reasons, the lack of transparency: "The government and the company Ponte sul Strait have not made public documents that are fundamental to understanding the extent of the project," said Bonelli. The report on the project was denied to parliamentarians, on the grounds that they are confidential and secret.
