Paul Biya, the world's oldest serving head of state, returned to Cameroon on Thursday after a 73-day absence that had intensified questions about his health and the country's governance. The 93-year-old president landed at the international airport in Yaoundé, the Cameroonian capital, aboard a flight from Geneva, Switzerland, where he had been staying since 7 June. His office had described the trip as a "short private stay in Europe," but the weeks stretched to more than two months — his longest recorded stay outside the country since he took power four decades ago. He left the airport alongside first lady Chantal Biya, waving from a car as it made its way to the presidential palace, greeted by dozens of ruling party supporters, some wearing clothing bearing his image.

Biya's prolonged absence dominated headlines and fuelled persistent rumours about his health, which have long circulated in connection with his frequent stays in Switzerland and France. On 18 June, Cameroon's Communication Minister René Emmanuel Sadi denied reports that Biya had been hospitalised at a Geneva clinic. In an apparent effort to signal continuity, the president signed a number of decrees during his absence, and official social media accounts continued to post messages in his name. An opposition lawmaker nevertheless petitioned the Constitutional Council to declare the presidency vacant, while senior ruling party figures insisted that state affairs continued to function normally.

The opposition painted a sharply different picture. Critics described the country as running on "autopilot," and prominent opposition figure Issa Bakary argued that the extended absence "only aggravates" a lack of presidential legitimacy. "Cameroonians widely believe that all is not well with the president," he said. Others were more dismissive of the significance of Biya's return. "It makes no difference whether he returns or stays away. When he is here, he does nothing," said Prosper Nkou Mvondo, leader of the opposition Univers party.

The episode has sharpened debate about what comes next for the Central African nation of nearly 30 million people. Cameroon has no vice-president — a post that has remained unfilled for months — meaning that the president of the Senate, Aboubakary Abdoulaye, would be next in line to lead in the event of a power vacuum, pending a new election. Biya's absence has accelerated speculation about potential successors and a post-Biya future. More than 70 percent of the population is under 35, and many young Cameroonians have grown up knowing no other leader.

Biya, who has led Cameroon since 1982, began an eighth term in November following an October election that triggered deadly protests after the main opposition candidate rejected the official result and claimed victory. Authorities acknowledged several dozen deaths in the crackdown on demonstrations, without providing a definitive toll. A 2008 constitutional amendment abolished presidential term limits, removing any formal barrier to Biya's continued rule. His return ends the immediate constitutional uncertainty, but the deeper questions about governance, succession, and the country's direction — beset by a Boko Haram insurgency in the north, a separatist conflict in the west, and a stagnant economy — are unlikely to fade.
