Thousands of South Koreans rallied in Seoul on Saturday demanding the resignation of President Park Geun-hye, as a crisis deepened over allegations a friend exerted inappropriate influence over her and interfered in state affairs.
The street protest came as prosecutors investigate presidential aides and other officials to determine whether they broke the law to allow Park's friend, Choi Soon-sil, to wield undue influence and gain financially.
Angry Koreans say Park betrayed public trust and mismanaged the government, and has lost a mandate to lead the country.
"She must step down," Lee Jae-myung, mayor of Seongnam city south of Seoul and a vocal critic of the government, said to a loud cheer from the crowd. "If Park Geun-hye is no longer president, will our lives be any worse off and will the tension with North Korea be any worse?" he asked the crowd, which responded "No!"
About 8,000 people attended the rally, according to police, organized by a group of left-leaning civic groups. Organizers said up to 30,000 people took part in the march through the capital.
"It's become clear the people made a wrong decision and picked a wrong president," Jeong Hong-woo, 22, told Reuters at the rally.
