Cuba's legendary leader Fidel Castro has taken his last bow as leader of the party he founded more than 50 years ago.

Joining us on the Riz Khan Show to discuss Cuba's future are Richard Gott, British journalist and historian and Eric Hershberg, Director at the Centre for Latin American and Latino Studies at the American University in Washington DC.
