After Marino held talks with prosecutors for over four hours on Monday, it was decided that he would not face further investigation over the scandal.
Speaking at a press conference on Tuesday, Marino suggested that now he was no longer under investigation he might try to remain in office, Corriere Della Sera reported.
“As the law dictates I have 20 days to consider my decision to resign,” he told reporters, suggesting that over the next 12 days he may try to see if he can drum up enough support within the city assembly to remain in office.
“On October 12th I signed a resignation following allegations over expenses. I resigned because I have the maximum respect for the law and I thank the prosecutors for listening to me,” continued the mayor, while insisting that the allegations were made by "deceitful and ignorant people".
Following the scandal, Marino's own Democratic Party finally lost patience with him following a string a high profile scandals and refused to back him.
The party is already grooming candidates for the next mayoral elections, due to be held in January, but what are the chances of Marino's name being put forward again?
“It's a very remote possibility,” leader of the Left Ecology and Freedom Party, Nichi Vendola, told Il Sole 24 ore.
