Acting Venezuelan president Nicolas Maduro has asked the country's election authority to call a vote immediately.
Officials are expected to announce the election date on Saturday as the South American country appoints a permanent successor to Hugo Chavez.
Mr Maduro, meanwhile, also named the late president's son-in-law Jorge Arreaza as his vice president during his time as interim leader.
More than 20 world leaders are expected to attend the funeral today, but there will be no burial as he will be embalmed.
Thousands flocked to the streets of Caracas to see the coffin of Chavez travel through the city to lie in state until Friday's funeral.
