Gbagbo announced the dissolution of both on Friday after a row with the commission over voter registration.

In his announcement, which plunged West Africa's former economic powerhouse deeper into crisis and is certain to delay an election scheduled for March, Gbagbo said he'd asked Prime Minister Guillaume Soro to propose a new government by Monday.

But an aide to the prime minister who declined to be named said that deadline would be unlikely to be met.

"I don't know when the prime minister will be ready, but it won't be tomorrow or Tuesday," said the aide. "It is too early and too complicated right now to take a quick decision."

The poll, which has been repeatedly postponed since 2005, is badly needed to end years of political instability following a 2002-3 war that split the world's top cocoa grower in two and stifled investment.

A peace deal signed in 2007 in Burkina Faso was meant to pave the way for elections and reunite the country.

Gbagbo also said he wanted Soro to propose a new electoral commission by Friday. Even if he meets that deadline, it could take a while to form one because all warring parties are supposed to agree on the commission's composition.

Many Ivorians fear violence this week, after opposition parties said they no longer recognized Gbagbo as president and called on their supporters to take to the streets in protest.

Gbagbo had accused electoral commission boss Robert Mambe, an opposition party member, of attempting to add 429,000 names to the voter register that did not have their Ivorian identity cross-checked in an attempt to boost the opposition vote.

Opposition candidates Henri Konan Bedie and Alassane Ouattara accuse Gbagbo of deliberately creating obstacles for the process to keep himself in power, a charge he denies.

After years of delays because of political bickering, some Ivorians are starting to doubt the polls will ever take place.
