Supporters are urging the world’s oldest leader, 91-year-old Cameroonian President Paul Biya, to run for office in the 2025 presidential election, potentially extending his more than four-decade rule.

They say Biya is the only one who can bring peace and development to the country, but the opposition says Biya must leave office after running Cameroon for decades.

Several hundred people sang in Cameroon’s capital, Yaounde, on Sunday, calling for Biya to accept the nomination of the Cameroon Peoples Democratic Movement, or CPDM party, in the 2025 presidential election.

Biya created the CPDM on March 24, 1985, three years after his predecessor, Cameroon’s first president, Ahmadou Ahidjo, stepped down due to ill health and handed power to Biya.

Biya has been president of Cameroon since 1982 and leader of his party since 1985.

During the party’s 39th anniversary on Sunday, party officials organized rallies in all Cameroon towns and villages to ask people to support Biya as their candidate in the 2025 elections.

Senior CPDM official Fru Jonathan described Biya as the party’s natural candidate, saying there is peace, unity and economic growth in the country. Jonathan said Biya is strong and healthy.

“We think that you don’t change a winning team,” Jonathan said. “If there is any challenger, let him come up, but we have not seen any challenger who can beat our candidate, so we all rely on him and call on him to continue to rule and bring our country to emergence as that is his vision.”
