Zanzibar debates autonomy as Tanzania election approaches

As Tanzania prepares to vote in general elections on Sunday, one of the burning issues on the archipelago of Zanzibar is the status of it union with the mainland.

The two sovereign states of Tanganyika and Zanzibar came together in the wake of independence from British colonial rule.

The union has allowed Zanzibar to remain semi-autonomous with its own president, but some are calling for more autonomy and more economic freedoms.
