A meeting between President Ashraf Ghani and his CEO Abdullah Abdullah has been postponed for unknown reasons, Abdullah's office said in a statement Saturday.

The meeting was planned by the president but the two leaders have not met yet," said Mujiburrahman Rahimi, spokesman to Abdullah.

Ghani and Abdullah were scheduled to meet Saturday in the wake of the recent backlash to discuss their issues.

"The meeting was planned by the presidential palace, but postponed over certain reasons, we are still prepared to hold the negotiations and wait for the presidential palace to be prepared," said Rahimi.

The statement comes a few hours after Abdullah defended his recent remarks against Ghani.

On Saturday, Abdullah met with his allies, including a delegation of Jamiat party members where the participants announced their support for him over his recent remarks agaist the president, and called for the swift and unconditional implementation of the political agreement.

The non-implementation of the political agreement, delaying the electoral reform agenda and monopolizing appointments appear to be the main reasons for the recent backlash between the president and his CEO.

"The best solution and the logical step is the implementation of the political agreement, bringing reforms in the election system, ensuring the rollout of electronic identity cards and appointments of the government positions in consultations between the two leaders," said Mohammad Natiqi, head of the political party.

"Centralization of power by the ARG (presidential palace) has caused the problem, not only the centralization of power, but a parallel government has emerged inside the ARG and authorities of the ministers have been reduced," said Rahimi.

Abdullah has also met the commander of foreign forces in Afghanistan general John Nicholson and a number of foreign diplomats in Kabul. At the meeting they have urged the CEO to settle the tension through talks and diplomacy.

"With consideration of current situations, there is a need that government leaders resolve their disputes, otherwise they will pave the way for the collapse of their government by their own hands," said MP Lalai Hamidzai.

There are some reports that Ghani's national security advisor and head of office of the president have met with the CEO, however outcomes of the talks have not been announced.
