Johannesburg – Officials are preparing for the possibility that all the overflow venues will be filled to capacity, and have asked that people co-operate if they were to be turned away.
Acting government spokesperson, Phumla Williams, said once the stadium were full, mourners would be directed to other overflow venues where large screens had been set up.
"We expect that at some stage all of these venues will be filled to capacity, and we therefore ask kindly that people co-operate with authorities if they were to be turned away," she said.
Large crowds converged on the FNB Stadium south of Johannesburg on Tuesday from the early hours for the official memorial service for Mandela, scheduled to start at 11:00.
People from all walks of life have come together around the world to celebrate former president Nelson Mandela's life.
"We view this as Madiba's legacy living on in the lives and values of people all over the world," Williams said in a statement.
In the past few days, people united in villages, towns and cities to share their love for Madiba, she said.
"As government, we want to thank South Africans and our friends and partners around the world for the overwhelming response...."
Mandela died at his Houghton home in Johannesburg on Thursday night, at the age of 95. He will be buried in Qunu in the Eastern Cape on Sunday.
Williams said that in South Africa, Madiba's legacy lived on in the democratic dispensation.
"Madiba's legacy lives on in our commitment to ensure a just and fair society for all."
Williams welcomed international royalty, heads of state and dignitaries to South Africa.
Friends, colleagues, comrades and family of Nelson Mandela are invited to share their memories and tributes, and to light a candle for him, on his profile at Remembered.co.za.
