A document found by investigators seems to indicate the coup plotters in Turkey planned to charge President Recep Tayyip Erdogan with aiding the banned Kurdistan Workers' Party (PKK), considered a terrorist organization.
The charges would have also been made against former prime minister and foreign minister Ahmet Davutoglu and Hakan Fidan, the head of MIT, Turkish intelligence, according to state-run Anadolu news agency and confirmed by a government official.
The alleged charge would have referred to the peace process - which ultimately collapsed last year - between the government and the PKK leadership, which began secretly in 2009.
In 2012, there was an attempt by prosecutors to question and arrest Fidan, who was leading the secret talks with the PKK.
Government officials have blamed Gulenists - who occupied positions within the judiciary - for the move against Fidan and it is rumoured that this was a key cause of tensions between Erdogan and the movement, which ultimately erupted into a full-blown schism.
