Tens of thousands of people protested in the capital Ankara on Sunday (September 14) against a court case that could oust the head of the main opposition on Monday after a year-long legal crackdown on hundreds of its members, Reuters reports.
Live footage showed crowds chanting for President Tayyip Erdogan's resignation while waving Turkish flags and party banners.
The court decision on Monday whether to invalidate the 2023 congress of the Republican People's Party (CHP) over alleged procedural irregularities could reshape the party, rattle financial markets and influence the timing of a general election set for 2028. The court could also delay the ruling.
Speaking at Sunday's rally, CHP leader Ozgur Ozel said the government was trying to cling to power by undermining democratic norms and suppressing dissent following opposition victories in local elections over the past year.
Ozel also called for a snap general election.
The government says the judiciary is independent and denies any political motives.
Turkey has detained more than 500 people, including 17 mayors over the last year in Istanbul and other CHP-run municipalities around the country as part of corruption investigations, according to a Reuters review.
Hundreds of members of the CHP have been jailed pending trial in a sprawling probe into alleged corruption and terrorism links, among them President Tayyip Erdogan's main political rival - Istanbul Mayor Ekrem Imamoglu.
The arrest of Imamoglu in March sparked the country's largest protests in a decade where hundreds of thousands took to the streets, prompting a brief but sharp selloff in the lira and other Turkish assets.
In a letter sent from prison and read aloud at the rally in Ankara, Imamoglu wrote that the government is attempting to pre-determine the outcome of the next election by sidelining legitimate rivals. He also accused the government of undermining democracy through politically motivated judicial actions and other efforts to suppress dissent.
"The era of 'I' in this country will end, and the era of 'we' will begin. One person will lose, and everyone else will win," Imamoglu wrote. The crowd applauded and chanted "President Imamoglu" after the letter was read aloud.
