The federal parliament in Mogadishu yesterday approved several constitutional changes that the government says are necessary to establish a stable political system.

Critics say the changes, which include introducing direct presidential elections and allowing the president to appoint a prime minister without parliamentary approval, concentrate power in the hands of the executive.

“Puntland will act independently until there is a federal government with a constitution that is agreed upon by a referendum in which Puntland takes part,” the state’s council of ministers said in a statement.

The rift is another headache for President Hassan Sheikh Mohamud, who is struggling to end an Al-Qaeda-linked insurgency, put down a resurgence in piracy and assert federal authority over the breakaway region of Somaliland after it agreed to lease a port to Ethiopia.
