A new leader was sworn in for Haiti’s transitional presidential council on Monday as it grapples with the fallout of serious corruption allegations against three of its members.

Leslie Voltaire replaces Edgard Leblanc Fils in the rotating presidency of the council, which was created this year after targeted gang attacks forced Haiti’s former prime minister to resign, leaving the country without a leader.

In a brief speech, Voltaire pledged transparency and noted that much work remains to be done in a country in the grip of rampant gang violence.

“We are not satisfied with the security situation,” he said. “We are working to reestablish security throughout the whole country.”
