Things fall apart

GOODLUCK JONATHAN, Nigeria’s president, was visibly stunned when a former vice-president, Atiku Abubakar, and seven state governors recently walked out of a convention of the ruling People’s Democratic Party (PDP) in open rebellion against his leadership. The party has won every election since it took power after the end of military rule in 1998. But it is bitterly divided over whether Mr Jonathan (pictured above) should run for a second full term in 2015. As a result, there is a chance—most analysts are wary of putting it more firmly—that, whether or not Mr Jonathan stays at its head, the PDP’s mighty cash-laden machine may lose power. And that could turn Nigerian politics upside down.
