Turkey’s president on Wednesday accused the political opposition of “sinking the economy” during the country’s largest protests in more than a decade over the arrest of Istanbul’s mayor, the biggest challenger to Recep Tayyip Erdogan’s 22-year rule.

Ekrem Imamoglu, the Turkish opposition figure whose detention this month triggered mass protests and a market selloff, criticized Western leaders for their muted response to his arrest.

More than 1,100 people, including some journalists, were detained in protests against Turkish President Erdogan after the arrest of his rival, Istanbul Mayor Ekrem Imamoglu.
