President Zuma's Nkandla home has grown

South Africa's President Jacob Zuma has agreed to repay some of the $23m the government controversially spent on upgrading his private residence - including building an ampitheatre, swimming pool, and cattle enclosure. 

Mr Zuma's decision came a week before South Africa's highest court, the Constitutional Court, hears a case brought by opposition parties to demand that he repays the money.

In papers filed in court, Mr Zuma said the auditor-general and finance minister should determine how much he should repay in order to "achieve an end to the drawn-out dispute". 

In 2014, South Africa's  Public Protector Thuli Madonsela said the president had "benefited unduly" from some of the upgrades, and he should repay the government for money spent on non-security features. 

The total cost of the security upgrades was estimated to be around $14m.
