Ousted Honduran president Manuel Zelaya said he would not accept anyone responsible for the June 28 coup to be part of a suggested coalition government, contradicting his earlier statement.
One of Zelaya's close aides in Nicaragua told reporters that the deposed president only agreed to setting up a unity government on the premise that he could retake the power and stay until the end of his term in January, 2010.
The personal advisor of Zelaya insisted other proposals remained as subjects for further negotiations.
A few hours earlier, Zelaya had said "yes" to the establishment of a power-sharing "government of reconciliation", as proposed by the Costa Rican
President Oscar Arias, the chief mediator of Honduras' crisis, during the second round of mediation talk held in San Jose on Saturday.
Zelaya said on Radio Globo he agreed to form a government in which all powers in the country are united.
Meanwhile, the interim government led by Roberto Micheletti rejected Arias' proposals immediately and refused to reinstate Zelaya.
