Cameroon's Biya set for 40 years at helm

Cameroon's 89-year-old president, Paul Biya, marks the 40th anniversary of his rise to power amid splashy ceremonies where the word on everyone's mind -- succession -- will almost certainly be absent.

The Cameroon People's Democratic Movement (RDPC), which Biya founded in 1985, says it will hold "a big party" up and down the country to mark the anniversary.

Biya rose to the top job on November 6 1982 after seven years as prime minister.

He is only the second president in Cameroon's history since the central African nation gained independence from France. He is also the continent's longest-serving leader after Equatorial Guinea's Teodoro Obiang Nguema Mbasogo, who seized power in 1979.

Commentators ascribe Biya's extraordinary political longevity to a mixture of astuteness and ruthlessness -- he has a constellation of loyalists in key positions and crushes or sidelines opponents and rivals.

But his public outings, except for a few choreographed TV appearances, have become rarer and rarer in recent years, stoking speculation about his health.

Any official talk of succession is taboo, and none of the most visible figures around Biya has publicly uttered a word about entertaining any wish to succeed him.

Even so, conversations about a successor are rife.

Those most commonly named are Biya's son, Franck Biya, and Finance Minister Louis-Paul Motaze. The younger Biya already has a discreet following among supporters called "Franckists."
