In October 2001, the CCM and the CUF parties signed a reconciliation agreement which called for electoral reforms and set up a Commission of Inquiry to investigate the deaths that occurred in January 2001 on Pemba. The agreement also led to President appointment of an additional CUF official to become a member of the Union Parliament. Changes to the Zanzibar Constitution in April 2002 allowed both the CCM and CUF parties to nominate members to the Zanzibar Electoral Commission. In May 2003, the Zanzibar Electoral Commission conducted by-elections to fill vacant seats in the parliament, including those seats vacated by the CUF boycott. Observers considered these by-elections, the first major test of the reconciliation agreement, to be free, fair, and peaceful. President Mkapa, Vice President Ali Mohamed Shein, Prime Minister Frederick Sumaye, and National Assembly members will serve until the next general elections in 2005. Similarly, Zanzibar President Karume and members of the Zanzibar House of Representatives also will complete their terms of office in 2005.
