In a speech to the Lower Chamber that was broadcast live on television, Lafontant defended his tenure but said that Haiti’s President Jovenel Moise had accepted his resignation.
“As I told you, I am at service to the Republic,” Lafontant said.
Earlier this month, the Haitian government announced a reduction of fuel subsidies as part of an agreement with the International Monetary Fund (IMF).
The move translated to a 38 percent rise in gasoline prices and 47 percent hike for diesel, triggering protests during which demonstrators barricaded roads, looted stores and set cars ablaze in the capital, Port-au-Prince.
The unrest caused embassies to close and airlines to suspend flights to Haiti for days.
