Abidjan - Ivory Coast President Alassane Ouattara on Tuesday named outgoing premier Daniel Kablan Duncan as the country's first vice-president.
Making his announcement before parliament, which was meeting in special session, Ouattara described the 73-year-old as "devoted, a loyal collaborator" and "a patriot and great servant of the state."
The new post of vice-president was set up under constitutional changes voted by referendum and approved in November.
Some analysts have said the new VP could be well-placed to step into Ouattara's shoes in the future.
Duncan's nomination comes a day after he and his government resigned following legislative elections in December.
A new prime minister has yet to be named.
Meanwhile former rebel leader Guillaume was re-elected parliament speaker on Monday.
Also on Monday, Ouattara fired the heads of the country's armed forces and police after a brief army mutiny that stoked security fears in the world's top cocoa producer.
