Turkey's main opposition Republican People’s Party (CHP) leader Kemal Kılıçdaroğlu filed a lawsuit against Interior Minister Süleyman Soylu over “threatening and insulting remarks.”

Kılıçdaroğlu’s lawyer Celal Çelik announced the legal action against Soylu through his Twitter account on Dec. 11, stating that his client seeks 100,000 Turkish Liras in compensation.

In a public address over the weekend, Soylu had slammed Kılıçdaroğlu saying: “I speak openly: Kılıçdaroğlu, you are finished.”

Soylu’s attack mainly focused on Kılıçdaroğlu’s allegations that President Recep Tayyip Erdoğan’s family members transferred millions of euros to a bank based on the tax haven Isle of Man. The minister accused the CHP leader of being a dishonorable man and a liar.

CHP spokesman Bülent Tezcan launched the initial counterattack, advising the minister to “get a medical report on his mental status” in a statement released on Dec. 10.
