In this Sept. 28, 2010, file photo, Cuba's leader Fidel Castro delivers a speech during the 50th anniversary of the Committee for the Defense of the Revolution, CDR, in Havana, Cuba. Castro said Tuesday, March 22, 2011, he resigned five years ago from all his official positions, including head of Cuba's Communist Party, a position he was thought to still hold.
The 84-year-old revolutionary icon made the revelation Tuesday - with word of the resignation thrown in as an aside halfway through an opinion piece that otherwise focused on President Barack Obama.
The declaration raises fundamental questions about just how much power Fidel has been wielding behind the scenes since his 2006 illness, and to what extent his 79-year-old brother has had freedom to make his own decisions as he pushed the country to enact sweeping economic reforms.
It also gives the Castros an opportunity to tap a possible future successor with their naming of a new party No. 2 - one without their famous last name.
They might select from a cadre of younger leaders who could carry the fiscal changes forward, and perhaps even reboot relations with the United States. Alternatively, the brothers could look to the past by promoting a loyal-but-weathered veteran of the revolution that brought them to power in 1959.
The answer will likely become apparent through a high-level game of musical chairs that Fidel's departure will engender in the upper reaches of the Communist Party hierarchy during a crucial Communist Party Congress next month.
