The imprisonment of Istanbul's opposition mayor has given President Recep Tayyip Erdogan the opportunity to target his most dangerous opponent, analysts say. Ekrem Imamoglu, the mayor of Istanbul, was detained and ordered to be jailed pending trial for graft offenses and terror-related charges. Erdogan's actions come at a time when Turkey is at the center of geopolitical turmoil, which has emboldened him and allowed him to neutralize the main threat to him in future elections. The convergence of international factors and domestic political considerations have contributed to Erdogan's move against Imamoglu.
