“There are new steps we will take in that sphere after March 30... including a ban (on YouTube, Facebook),” Erdogan told private ATV television in an interview late Thursday.

In stark contrast, President Abdullah Gul, a frequent social media user, said Facebook and Youtube cannot be unplugged.

“Youtube and Facebook are recognised platforms all over the world. A ban is out of the question,” he told reporters on Friday.

The president in Turkey is, however, a largely ceremonial figure.

Erdogan, Turkey’s all-powerful leader since 2003, has been under mounting pressure after audio recordings were leaked last month in which he and his son allegedly discuss how to hide vast sums of money.

The Turkish premier dismissed them as a “vile” and an “immoral” montage by rivals ahead of key local elections on March 30. His office claimed the recordings were “completely untrue”.

A series of other leaks on YouTube showed Erdogan allegedly meddling in trade deals and court cases.

Erdogan’s government has been shaken by a high-level corruption scandal that erupted in mid-December and ensnared the premier’s key political and business allies.

Erdogan has waged a war against ally-turned-opponent Fethullah Gulen, a Muslim cleric based in the United States with strong influence over the country’s police and the judiciary, of orchestrating the graft probe.

He has accused so-called “Gulenists” of acting like a “parallel state” and vowed to cleanse the state of the movement’s supporters by purging police and passing laws to increase his grip over the Internet and the judiciary.

“Social media has turned into a domain for quite some time where the battle between the loyalists of the frustrated prime minister and the alleged ‘parallel state’ is in full swing,” Asli Tunc, professor at Istanbul’s Bilgi University, said.

“The government is seeking to find channels to shut down the social media which leaks tapes or dissident views. People cling to social media tools like Twitter for their news because the mainstream media or TVs are cowering in fear,” she said.

Erdogan’s latest threat about Facebook and YouTube is a reflection of his political frustration in the run up to elections, according to Tunc, but she said the premier was also known for his intolerance toward the social media.

Erdogan is openly suspicious of the Internet, branding Twitter a “menace” last year for helping organise mass anti-government protests in which eight people died and thousands were injured.

“I don’t have that much time to waste in Twitter,” he said last month.

Tunc said that in undemocratic countries governments tended to control the social media because its dynamic structure “runs contrary to their policies”.

Access to thousands of websites have been blocked in recent years in Turkey.

YouTube was previously banned for two years until 2010 because of material deemed insulting to the country’s still-revered founder, Mustafa Kemal Ataturk.

The site still managed to be one of the most visited in Turkey, with users including Erdogan himself resorting to proxy servers to dodge the ban.

“I can get in (YouTube), you can too”, Erdogan famously said at the time, referring to those servers that provided a backdoor to the site.

Further internet curbs allowed the authorities to keep a record of someone’s web activity for up to two years and block sites deemed insulting or as invading privacy, which critics denounced as “Orwellian”.

Critics say, however, that the latest curbs are aimed at preventing further details from the corruption scandal being leaked online.

The European Union has voiced its “concerns” that the Internet law would limit freedom of expression, urging Ankara to ensure compliance with the bloc’s standards.
