Turkey's main opposition Republican People's Party (CHP) leader Kemal Kilicdaroglu launched a European court appeal over an April vote that granted the country's President Recep Tayyip Erdogan sweeping powers.
Before starting the 20th day of his march, CHP head Kemal Kilicdaroglu signed an appeal to the European Court of Human Rights against the decision by Turkey's YSK election board to accept unstamped ballots in the April 16 referendum.
"The YSK decision made the referendum illegitimate. We are applying to the European Court of Human Rights," Reuters cited Kilicdaroglu as saying.
April's referendum, held under a state of emergency, gave a narrow 51.4% approval for constitutional changes that sharply widened Erdogan's presidential authority.
Opposition parties have said the poll was deeply flawed, while European election observers said the decision of the High Electoral Board (YSK) to allow unstamped ballot papers to be counted had removed a main safeguard against voting fraud.
