The 69-year-old leader gave three campaign speeches ahead of the parliamentary and presidential election set to take place on May 14.
After these, he appeared to live for a joint interview with Ulke TV and Kanal 7, news agency AFP reported. The television appearance began over 90 minutes behind schedule. It was cut off in the middle of a question ten minutes into the show.
In the live version, the camera shook and the reporter asking the question stood up from his chair. The broadcast was then cut off. "Oh wow," an unidentified voice was heard saying off camera.
Erdogan returned 15 minutes later to apologise for getting sick, AFP reported.
“Yesterday and today were hard work. That's why I got a stomach flu. At one point, I wondered if it would be misunderstood if we cancelled the programme. But we promised. I ask for your and our audience's forgiveness,” Erdogan said as his face looked tired and his eyes appeared to water as he spoke.
After this, the leader took a few more questions before ending the broadcast.
