Willem de Klerk, the son of former president FW de Klerk, has died.

The FW de Klerk Foundation announced the 53-year-old's death on Wednesday.

“It is with the deepest sadness that FW de Klerk announces that his son, Willem, died last night in Durbanville after a courageous battle against cancer. The family will, in due course, make a further announcement regarding funeral arrangements,” said the foundation in a brief statement.

This is a developing story.
