NAIROBI - Tanzanian opposition leader Freeman Mbowe called on Sunday for the new government to prioritise a new constitution, reviving calls for limiting presidential powers.

Mbowe, chairman of Chadema, the country's main opposition party, said in a speech the current constitution gives “someone the chance to be a dictator or a king", adding it should be a government priority to set a timetable and a procedural framwork to change the consitution.
