Johannesburg - The FW de Klerk Foundation expressed sadness on Monday at the death of Nobel Laureate and writer Nadine Gordimer.

“The FW de Klerk Foundation has learned with sadness of the death of Nadine Gordimer,” it said in a statement.

“She continued to be critical of unconstitutional behaviour from any quarter in South Africa and was particularly opposed to any steps that might limit the freedom of the press.”

The foundation said Gordimer's voice would be missed by all South Africans.

“However, her literature will remain with us forever. The FW de Klerk Foundation and FW de Klerk would like to convey their sincere condolences to Ms Gordimer's family and friends.”

Earlier on Monday, law firm Edward Nathan Sonnenbergs said in a statement on behalf of the Gordimer family: “Her son Hugo and daughter Oriane and her caring helpers were with her... A private memorial service will be announced at a later date.”

It said she died “peacefully in her sleep at home in Johannesburg on Sunday”.

Gordimer was 90 years old.
