ANKARA, Jan 18 (Reuters) - Turkey has extended a purge of official bodies to the banking and telecoms regulators and state TV, firing dozens of executives in moves that appear to broaden Prime Minister Tayyip Erdogan's backlash against a corruption investigation.
The authorities have already sacked thousands of police officers, dozens of prosecutors and some state television officials in response to the corruption investigation, which has become the biggest challenge to Erdogan's 11-year rule.
Investigators are believed to have been looking into allegations of corruption at a state-run bank and bribery involving big real estate projects, although details of their charges have not been made public.
The combative prime minister says the investigations, which began a month ago with arrests of high profile figures including the sons of three of his cabinet ministers, are part of an attempted "judicial coup".
His opponents say they fear a purge of official bodies will destroy the independence of the judiciary, police and media.
"It's like reformatting a computer. They are changing the whole system and people in various positions to protect the government," said Akin Unver, assistant professor of International Relations in Istanbul-based Kadir Has University.
Among dozens of officials dismissed in the latest sackings, Turkish media reported on Saturday that the deputy head of the banking watchdog BDDK and two department heads had been removed.
Five department chiefs were fired at the Telecommunications Directorate (TIB), a body that carries out electronic surveillance as well as serving as telecoms regulator, and a dozen people were fired at Turkey's state channel TRT, including department heads and senior news editors.
A government official said the firings were carried out for "the benefit of the public" and more could come: "Right now we are working on this issue and if we identify cases problematic to the public's benefit, more dismissals could be considered."
Pictures of money-counting machines and reports of cash stacked in the homes of people linked to the graft probe have caused uproar among the Turkish public.
Unver said the aim of the purge at the telecommunications watchdog could be to prevent further videos and pictures being published on the Internet by tightening the government's grip.
"They are seeking a monolithic structure over the Internet," he said.
Erdogan has suggested the graft inquiry, which has led to the resignation of three cabinet ministers and detention of businessmen close to the government, is an attempt to undermine his rule by Fethullah Gulen, a U.S.-based cleric with influence among the police and judiciary.
Many of the people who have been fired are believed to be associated with the cleric's Hizmet movement, which claims more than a million followers and runs schools and charities throughout Turkey.
Gulen's lawyer says the cleric has nothing to do with the graft investigations, and his followers say they are victims of a witch hunt.
Earlier in the week the government reassigned twenty high-profile prosecutors, stepping up the purge of the judiciary.
The government has also prepared a draft bill to tighten its grip on High Board of Judges and Prosecutors (HSYK), a panel that controls the appointment of all judges and prosecutors.
There were heated arguments and even fistfights among members of parliament during talks on the draft bill last week.
Erdogan, who has presided over an extended economic boom that has transformed Turkey and lifted millions of people from poverty, remains the country's most popular politician.
He and his moderate Islamist AK Party have long battled for influence against the secularist military establishment that dominated Turkey over the past century. Conflicts with the judiciary, police and Gulen followers add to his list of enemies.
It is still not clear what effect the crisis will have on Erdogan's political fortunes ahead of local elections approaching in March. Last year saw mass street demonstrations among Turks who accuse the prime minister of authoritarianism, but those protests did little to undermine Erdogan's support among his conservative base of followers.
