Despite an unexpectedly energetic start, misfortunes haunted Republican People's Party (CHP) chairman Kemal Kılıçdaroğlu's march on its fourth day, including a severe injury that ended in hospital.
"We are marching for justice, not against it," Kılıçdaroğlu said.
Shortly after the group began the march amid hot and humid weather, a 65-year-old party member suffered a heart attack, collapsed and took severe injuries due to head trauma.
Initial media reports suggested that the man died from his injuries. A statement from the Health Ministry said that units in ambulances that followed the group initially responded to the man suffering from cardiac arrest at the scene. The man was rushed to the Kazan State Hospital and remains in critical condition.
Later in the day, 69-year-old Kılıçdaroğlu saw a group of people gathered to support the march on a ridge next to the Ankara-Istanbul highway. The CHP leader got off the road and went next to the group. While trying to descend from a steep ridge, Kılıçdaroğlu fell and drifted briefly before he was back on his feet with the aid of his bodyguards, luckily without any injuries.
Despite the unpleasant fall, Kılıçdaroğlu kept calm and the march resumed as planned.
Kılıçdaroğlu launched the 400-kilometer march from Ankara to Istanbul Thursday, a day after one of its deputies was given a prison sentence on espionage charges.
The march came as a protest after CHP's Istanbul deputy Enis Berberoğlu was sentenced to 25 years in jail for leaking secret documents to the press in the controversial National Intelligence Organization (MIT) trucks case. Berberoğlu was accused of supplying confidential footage of a raid on MIT trucks, carried out by the Gülenist terror group (FETÖ), to Cumhuriyet daily's former editor-in-chief Can Dündar and its Ankara representative Erdem Gül.
In May last year, the Turkish parliament voted to strip lawmakers facing trial of their parliamentary immunity.
