The main change was the replacement of Etienne Massard Kabinda Makaga as defence minister with the mayor of Libreville, Rose Christiane Ossouka Raponda.

Makaga, who had held the post since 2016, is a member of the Bongo clan.

Biendi Maganga Moussavou, son of Vice President Pierre-Claver Maganga Moussavou, recovered the agriculture ministry portfolio he lost in the reshuffle two weeks earlier to Ali Akbar Onanga Y'Obeghe.

Norbert Emmanuel Tony Ondo Mba became energy minister, replacing Christian Magnagna.

"This is a 'reorganisation' of the government, not a reshuffle," said the president's office.

Ali Bongo returned to Gabon for just 24 hours earlier this month for the swearing in of the previous ministers before returning to Morocco where he has been recovering from his illness.

Just a week before that visit, a small group of soldiers briefly tried to stage a coup before it was quashed by security forces, who arrested the leader and killed two others.

The newly appointed ministers will not take their oaths in front of President Bongo, said a source in the president's office.

The oil-rich West African state has been without an effective government for months since Bongo, 59, suffered the stroke in late October during a visit to Saudi Arabia.

After initial treatment at a hospital in Riyadh, Bongo was transferred to Morocco, officials said.

Bongo has not been seen in public since being taken to hospital on October 24, though video of the swearing-in ceremony earlier this month offered a few brief shots of him, seated in a wheelchair and squinting slightly.

That appearance has failed to quell speculation about his health.

The Bongo family has governed Gabon for five decades, and long maintained close ties with former colonial master France.

Ali Bongo was elected head of state after his father's death in 2009. He was narrowly re-elected in 2016 following a presidential poll marred by deadly violence and allegations of fraud.
