Yemen's president Ali Abdullah Saleh was expected to sign an agreement on Saturday that aims to end three months of unrest in the country.
But a government spokesperson says talks about whether he will do that, are "ongoing".
The opposition is expected to sign the agreement on Sunday.
Al Jazeera interviews Jamila Ali Raja, a Sanaa-based political activist and the former spokeswoman for the Yemeni foreign ministry, about the negotiations.
