The presidential swearing-in ceremony has been postponed until this Monday afternoon, Presidential Palace spokesman Sediq Sediqqi said.
Ghani was announced the winner by the Independent Election Commission (IEC) on February 19.
Chief Executive Abdullah Abdullah, contesting the IEC’s decision, plans to hold a swearing-ceremony for himself as well.
Hours after the announcement of the final results in February, Abdullah announced the formation of an “inclusive government” by his Stability and Convergence campaign team, declaring his “victory” in the polls.
Abdullah said decisions on disputed votes were “illegal,” adding that the IEC’s results were a coup against democracy and that he does not accept them.
On Sunday, Abdullah’s office confirmed that US special envoy Zalmay Khalilzad on Monday held three meetings with the chief executive to “find a solution” for the matter but apparently did not succeed. Despite that, Abdullah’s deputy spokesman, Fraidoon Khwazoon, said hopes still remain.
Khwazoon said efforts are underway by Afghan and foreign politicians to end the crisis.
Late Sunday night sources told TOLOnews that President Ghani and CE Abdullah had met, but sources said no agreement had been reached on the election standoff.
Afghan politicians remain concerned about the future of an attempt to hold two oath-taking ceremonies in a single day, believing it will lead the country into a new crisis.
In September 2014, Ghani shared the power with Abdullah Abdullah who becomes chief executive and formed together the national unity government.
