Venice Mayor Luigi Brugnaro is at the center of a corruption investigation that has rocked the city's administration.

Prosecutors allege a web of conflicts of interest, including a fictitious blind trust for Brugnaro's business interests and the sale of historic buildings at below-market prices.

The mayor's close associates, including his chief of staff, are accused of using secure phones provided by a city-controlled company to evade wiretaps.

The probe has also uncovered alleged attempts to influence environmental assessments for valuable land deals.

Critics are calling for Brugnaro's resignation, with protesters unfurling a 'Brugnaro Resign' banner during a recent public event.

The scandal has raised questions about the ethical standards in Venice's governance and the blurred lines between public service and private gain.
