Sunday's "Democracy and Martyrs' Rally" in Istanbul, which will be held in protest against the July 15 foiled coup by the Gülenist Terror Organization (FETÖ) will be broadcasted live.
The mass rally will be held in the port city's Yenikapı district and will be broadcast simultaneously in seven languages, including Turkish, English, French, Spanish, German, Russian and Arabic.
President Recep Tayyip Erdoğan, Prime Minister Binali Yıldırım, who is also the leader of the ruling Justice and Development (AK) Party, as well as the main opposition Republican People's Party (CHP) leader Kemal Kılıçdaroğlu and Nationalist Movement Party (MHP) leader Devlet Bahçeli are expected to attend the rally set to start at 5 p.m. local time (1400GMT) on August 7.
The Yenikapı event will culminate weeks of "democracy watch" rallies held in cities across the country since the deadly coup attempt, which martyred at least 240 and wounded nearly 2,200 people, on July 15.
A huge stage will be erected in Yenikapı, as well as big television screens and sound systems will be installed. Around 13,000 people, aside from police officers, will be on duty to organize the event and perform other technical duties. Helicopters, ambulances and over 700 medical personnel will also be posted for healthcare services.
Similar rallies will also be held simultaneously all across the country, AK Party officials said earlier.
The public gatherings are expected to attract people from all walks of life, regardless of their political preferences.
Turkey's government has repeatedly said the defeated attempt was organized by followers of Fethullah Gülen, who has lived in self-imposed exile in the U.S. state of Pennsylvania since 1997.
Gülen is also accused of leading a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police, and judiciary, forming what is commonly known as the parallel state.
