Afghan CEO Abdullah Abdullah on Sunday said at a meeting at the Presidential Palace that the National Unity Government (NUG) will not end this week, when it marks its two-year anniversary.
He said the government will still be legitimate and that it is valid for five years.
"The rumors that say NUG will not be valid upon completion of its second year, are wrong," Abdullah said.
This comes amid concerns that the NUG would no longer be legitimate after Thursday due to non-compliance of the agreement signed between Abdullah and President Ashraf Ghani at the time of its establishment in September 2014.
According to the agreement, the leaders should have convened a Loya Jirga to amend the constitution to include the position of prime minister. However this has not been done.
"The NUG leaders need to fulfill their commitments they made to the people," said Abdul Subhan Misbah, a member of Afghanistan Lawyers' Union.
The NUG leaders once again met on Sunday night; but the Presidential Palace and the CEO's office said the meeting did not focus on the recent rift between the two leaders.
However, at the launch of the Citizen's Charter in Kabul on Sunday, Ghani told the guests present that a "president is like a kite, as much as it goes high; its string is in the hand of the people. People can decide to pull us to the ground or let us climb to the sky," said Ghani.
While the NUG also rejects claims of a rift between the leaders, a number of former government officials and MPs have said the delay in implementing the political agreement has been rooted in the tension between the leaders.
"If there was no disagreement, the work would go smoothly. You know that currently the NUG leaders have serious disagreements," said Mohammad Amin Farhang, a political analyst.
"Electoral reforms and holding of parliamentary elections was one of the commitments of the leaders. But you know that more than one year has passed from the time the election should have been held. As the election is delayed, the institutions responsible for holding the election get weaker and government also wants to have parliament under its control," said Fawzia Kofi, head of parliament's women's commission.
Opposition groups and political analysts meanwhile said that political legitimacy of the NUG will come under serious question, but the leaders say that NUG is valid for five years.
