Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Former Nigerian president Olusegun Obasanjo, who is in the country with the biggest team of observers to be deployed in KwaZulu-Natal, has urged political parties to "accept the will of the people".
Some members of the African Centre for Conflict Resolution of Disputes (Accord) attended rallies held in the province on Sunday as parties wrapped up their campaigns ahead of tomorrow's elections.
A large contingent of police has been deployed in the north, the Midlands and the South Coast to monitor the elections.
Addressing the media at Durban's International Airport yesterday morning, Obasanjo said it was important that the outcome of the elections was accepted.
"As an African continent we should not be an exception for democracy, but in the mainstream of a democratic process.
"If we look back at our history, even before there was a democracy, our forebears were democratic.
"They consulted, had consensus and allowed suggestions or input from various sectors of society. That in its own was democracy," he said.
"People must feel that they have participated freely in a democratic process. People must have a general good feeling about elections and playing a role in them.
"We are not here to be judgmental but to observe and to ensure that the results are generally acceptable," he said.
Obasanjo will meet President Kgalema Motlanthe, IEC chairperson Brigalia Bam and visit former president Nelson Mandela.
Tomorrow he will meet IFP leader Mangosuthu Buthelezi and see him cast his vote in Mahlabathini. Later he will meet ANC president Jacob Zuma at Nkandla.
"I want to wish you a success, your success is the success of the whole of Africa," he said.
