"Every citizen should be allowed to vote, the commission can close only when the last person votes," Romero said, explaining that some polling stations were still open as people were still waiting in line.
Bolivia’s Interim President Jeanine Anez called on citizens and political parties to have patience as they wait for official voting results.
"We should all have patience as we await the results of the election and not engage in acts of violence. We will have results that we can trust," Anez said on Sunday, as broadcast by the Pagina Siete daily newspaper.
Earlier on Sunday, Romero announced the opening of polling stations in Bolivia, saying that masks and sanitizers would be available.
On Saturday, Romero assured reporters that vote counting would be carried out transparently and in line with the law and anybody, including journalists and international observers, would be able to monitor the process and take photos of polling station statements on votes.
According to the latest polls, Luis Arce Catacora, the nominee of former president Evo Morales’ Movement to Socialism (MAS) party, is ahead of centrist former president Carlos Mesa and other presidential candidates.
Romero said on Saturday that official voting results should not be expected on Sunday night as vote counting would take some time.
Bolivia has experienced political turmoil since Morales stepped down in November of last year, after a controversial presidential election. Most of Bolivia’s senior officials resigned in his wake. The Bolivian opposition, led by Carlos Mesa, claimed that there were mass violations during the October 2019 vote.
