Liberians choose new president as Sirleaf steps aside
What you need to know:
Sirleaf will step down after 12 years at the helm of Africa's first republic, whose back-to-back civil wars (1989-2003) and Ebola crisis (2014-16) have stunted growth and left Liberia among the world's poorest nations.
Twenty candidates are vying to replace Sirleaf, with footballing icon George Weah, incumbent Vice President Joseph Boakai, longtime opposition figure Charles Brumskine and soft drinks millionaire Alexander Cummings considered front-runners.
