In a harshly worded response to diplomatic cables released by WikiLeaks, Turkey’s Prime Minister Recep Tayyip Erdogan said that he will file legal action again U.S. envoys he accused of making false claims against him.

Speaking during a municipal ceremony in Ankara, Erdogan called on the U.S. administration to take action to discipline the diplomats who “slandered” him in the leaked State Department documents.

A leaked cable signed by former U.S. envoy to Ankara Eric Edelman claimed that Erdogan had eight secret accounts in Swiss banks, a claim the American diplomat said had been made to the U.S. Embassy by two contacts. He did not give further evidence. Other documents accused Erdogan of reaping personal gain from a billion-dollar privatization.

In addition to criticizing the U.S. administration and its envoys, Erdogan also slammed the Turkish media and the head of the main opposition for publicizing the allegations, Hurriyet Daily News reported.
