Cameroon President Paul Biya has been outside the country for two months, raising concerns about his health.

Axar.az informs, citing The Associated Press, that his prolonged absence has also sparked criticism over a possible power vacuum in the Central African nation.

The world’s oldest president, who has led Cameroon since 1982, began his eighth term in office in November after winning a widely disputed election in October.

But the 93-year-old left the country on June 7 for what Biya’s office described as “a brief private stay in Europe” that has become one of his longest trips overseas.

His government later confirmed he was in Switzerland.

It should be noted that Paul Biya has led Cameroon since 1982.
