Turkey's main opposition leader on Sunday pledged further protests against the jailing of Mayor Ekrem Imamoglu, President Tayyip Erdogan's chief rival, aiming to sustain Turkey's biggest demonstrations in more than a decade.

The Turkish opposition will fight "until the end" against President Recep Tayyip Erdogan, the leader of the opposition CHP party told AFP in an interview Wednesday, accusing the head of state of staging a "coup" with the arrest of Istanbul's opposition mayor.
