Turkish President Recep Tayyip Erdoğan is suing the main opposition Republican People’s Party (CHP) Chairman Kemal Kılıçdaroğlu over “slanderous” comments about him and his family, the state-run Anadolu news agency reported.

According to the news portal, on Friday, Erdogan’s lawyers filed a lawsuit with an Istanbul civil court for 1.5 million Turkish liras ($380,000) in compensation for “spiritual damage” from Kılıçdaroğlu.

The lawsuit came days after Kılıçdaroğlu asked whether Erdogan was “aware” that his family were “sending millions of dollars of money to tax havens.”

“Do your children have millions of dollars sent to overseas accounts?” Kılıçdaroğlu asked during the CHP group meeting in parliament on Tuesday.
