Anadolu Agency says an Istanbul court today charged Osman Kavala with attempts to abolish the constitutional order and Turkey's government.
Kavala is the latest activist to be held in a massive government crackdown begun after the coup in which 50,000 people have been arrested and more than 110,000 purged from government jobs.
The businessman, a long-time rights activist who has been involved in peace and reconciliation initiatives, was taken under police custody on October 18.
