Celebrating honest public officials
Integrity Idol started in Nepal in 2014. The competition is now conducted by volunteers in Liberia, Pakistan, Mali and South Africa.
The event is based on "faming, not shaming." Instead of focusing directly on corruption, they highlight integrity.
"The more we can show that government officials can be celebrated for doing the right thing, the more it will help the public understand what they should expect from them," Glencorse told CNN in 2016
after the Liberian Integrity Idol.
Each country narrows down five candidates who are filmed and interviewed for national television and radio.
Throughout the week citizens vote online and via SMS.
