A top aide to ousted Honduran President Manuel Zelaya says negotiations to solve the country's three-month old political crisis are once again at an impasse.

Negotiator Victor Meza accuses the interim government of obstructing progress by insisting that Congress and the Supreme Court be consulted on whether Zelaya can be reinstated. The court has already said Zelaya should not be allowed to return.

Meza said Monday that Zelaya's team will not return to the table until Roberto Micheletti's government presents a "constructive proposal." But he added that they will not break off talks entirely.

Zelaya was ousted June 28 after he defied Supreme Court orders to cancel a referendum on a constitutional rewrite.
