(QHA) -

Protests erupted in Istanbul and Ankara on Tuesday after news broke of tape recordings, allegedly of Turkish Prime Minister Recep Tayyip Erdogan ordering his son to dispose of  $30 mln of cash, Euronews reports.

It’s the latest episode in a probe into the financial affairs of Cabinet ministers that began on December 17.

Several minister’s sons were held on charges of corruption, bribery and money laundering.

The main opposition Republican People’s Party claims to have authenticated the recordings, but Erdogan denies this.

He told parliament:

“This is a treacherous attack against the Prime Minister of the Turkish Republic. I would like to underline this is not an attack against Recep Tayyip Erdogan or the leader of the AK Party. This is a callous attack against Turkey’s Prime Minister.”

Erdogan’s official website also denies the allegations, dismissing them as “fabricated”.
