Witness statement ‘’...I have not witnessed any irregularities in a concrete way, but I have some rumours since I am in the sector.‘’
By the way, most of the charges are based on "secret witnesses" the same method as Ergenekon- Balyoz (Sledgehammer) cases.
Anyway, I have zero doubt that İmamoğlu is corrupt just like Erdoğan but you can't remove an elected metropolitan mayor by weaponizing the judiciary unless it is high treason. Erdoğan stole billions and everybody knows this but it is not right for some random judge to have the power to remove him because people elected him. Corruption charges if there are any should be pressed after politicians are voted out of office unless it involves high treason or murder etc.
