Turkey denies offering cash for plan to extradite Gulen

Turkey has rejected as "ludicrous" allegations that it offered several million dollars to the United States to extradite a political rival to President Recep Tayyip Erdogan.

US media reported that investigators in Washington are probing whether former White House national security advisor Michael Flynn discussed expelling Muslim preacher Fethullah Gulen in exchange for a secret payout.

Ankara blames Gulen's movement for the 15 July 2016 failed coup against Erdogan, and has pressed for his extradition from the United States, where he has lived since 1999.

Gulen, who has a large Turkish following, strongly denies the charges.

"All allegations that Turkey would resort to means external to the rule of law for his extradition are utterly false, ludicrous and groundless," Turkey's embassy in Washington said on Twitter Saturday.

NBC News and the Wall Street Journal said on Friday that US Special Prosecutor Robert Mueller is examining a meeting Flynn had with senior Turkish officials weeks after Donald Trump won the presidential race last year.

The meeting allegedly discussed a secret payout of up to $15m if, once in office, Flynn would engineer the deportation to Turkey of Gulen as well as help free Erdogan-linked Iranian-Turkish businessman Reza Zarrab from prison.

NBC and the Journal both cited multiple people familiar with the probe by Mueller, who is leading the investigation into whether members of Trump's campaign colluded with Russian meddling in the election.

The Journal said it is not clear how far the proposal went and that there was no sign that any payments were made.

Lawyers for Flynn have labelled the allegations "outrageous" and "false". 

Also rejecting the allegations was Turkish businessman Ekim Alptekin, who described the claims as "fabricated" to state-run Anadolu Agency.

The Wall Street Journal said Alptekin had been responsible for organising a meeting between Flynn and Turkish representatives in 2016. 

"Turkey and the possible bilateral relations with the US - and nothing illegal - were discussed in the meeting," said Alptekin, who is also chairman of the Turkey-US Business Council.

"The only purpose of levelling these fabricated allegations is to damage Turkey’s reputation. I regret seeing some respected media outlets crediting these lies - no doubt, the truth will come out and embarrass those who promoted these lies."

According to the two reports, the discussions included details of how Gulen could be flown secretly by private jet to the isolated Turkish prison island of Imrali, which currently also holds Abdullah Ocalan, leader of the outlawed Kurdistan Workers Party (PKK).
