A transitional council tasked with choosing new leaders for Haiti is changing the way it operates in a move that surprised many as gang violence consumes the country.

Instead of having a single council president, four longtime politicians will take turns leading the council every five months, according to two members who were not authorised to publicly share the changes because they had not yet been announced.

The members said late on Wednesday that the council also will now consider five members a majority, instead of four. The council is composed of nine members, seven of which have voting powers.

“That’s a real switch,” Robert Fatton, a Haitian politics expert at the University of Virginia, said of the changes. “I think it’s a good thing that they’re really going to share power now. … It is something that is very rare in Haitian politics.”

The four members who will share power are original council president Edgard Leblanc Fils, ex-senator Louis Gérald Gilles, former presidential candidate Leslie Voltaire and ex-ambassador for the Dominican Republic Smith Augustin.

The changes follow inner turmoil that threatened to derail the council after it was sworn in on April 25. The bickering began five days later, when four council members announced not only a council president but also a prime minister to the shock of many.

However, it remains to be seen if former sports minister Fritz Bélizaire will remain as the chosen prime minister. One council member said they expect to make an announcement next week.

After a prime minister is announced, the council expects to choose a new Cabinet, a process many expect will involve long and heavy negotiations with powerful politicians.

“That’s going to be the other major issue,” Fatton warned.

The changes come as Haiti prepares for the UN-backed deployment of a Kenyan police force to help fight gangs that have decimated swaths of the capital of Port-au-Prince.

On February 29, gangs launched coordinated attacks; they burned police stations, opened fire on the main international airport that has remained closed since March 4 and stormed Haiti’s two biggest prisons, releasing more than 4,000 inmates. The country’s largest seaport also remains paralyzed as food, medication and other critical items dwindle.

At least 1.4 million Haitians are on the verge of famine, according to the UN’s World Food Programme. US military planes have landed in recent days with supplies including medicine and oral hydration fluids as well as civilian contractors to prepare for the arrival of foreign forces, although it’s not clear exactly when the Kenyan police would deploy.

A team of top Kenyan security officials are in Washington DC this week to finalise deployment plans, including the number of police that will be sent. As Haiti awaits foreign forces, gang violence has surged in recent days. They have attacked several communities near downtown Port-au-Prince, forcing more than 3,700 people to flee their homes.

On Tuesday, at least four people died and several others were injured when someone opened fire on a bus driving through Martissant, a gang-controlled area in southwestern Port-au-Prince.

Kidnappings also have increased, with a female police officer killed Wednesday morning while trying to fight off gangs who tried to abduct her, said police union leader Lionel Lazarre.

More than 2,500 people have been killed or injured in the first three months of the year, a 50% increase compared with the same period last year, according to the UN.
