President Cyril Ramaphosa is expected to deliver the eulogy at the State Memorial Service of former President FW de Klerk in Cape Town on Sunday.
De Klerk died of cancer last month at the age of 85.
He was laid to rest at a private funeral service more than two weeks ago.
Government says that the service will take place at the Groote Kerk, and attendance will be limited due to COVID-19 regulations.
De Klerk’s death brought with it much debate over his legacy and contribution to the country’s democracy.
A look at De Klerk during the apartheid years:
In his last address to the public, which was posted after his death on his foundation’s website, De Klerk apologised for the damage caused by apartheid despite previously disagreeing that apartheid was a crime against humanity.
Government says it will be on the lookout for possible protests during the memorial saying the unity of the country is important.
