South African President Cyril Ramaphosa is facing a possible impeachment threat over the "Farmgate" scandal.
The president has been accused of covering up a $4m (£3.3m) theft from his farm in 2020, including kidnapping and bribing the burglars into silence.
He has denied wrongdoing, and said the money was from selling buffalo.
The panel's findings have been handed to parliament, which is set to examine them and decide whether or not to launch impeachment proceedings next week.
Mr Ramaphosa is less than a month away from a conference which will decide if he can run for a second term with his party, the African National Congress (ANC), in 2024. The incident could be particularly damaging as Mr Ramaphosa ran for office on an anti-corruption ticket.
The ANC will hold a meeting with its executive on Thursday, where it is expected that the issue will be discussed.
The Farmgate scandal erupted in June, when a former South African spy boss, Arthur Fraser, filed a complaint with police accusing the president of hiding a theft of $4m in cash from his Phala Phala farm in the north-east of the country in 2020.
Holding such a large amount of money in dollars could violate foreign exchange control laws.
Mr Ramaphosa has confirmed a robbery, but said the amount stolen was less than that alleged, and denied attempting to cover it up.
Some $580,000 which had been paid in cash for buffalo was stolen from under sofa cushions in the farmhouse, he said.
