President Ramaphosa allegedly he failed to report a heist at his luxury cattle farmhouse in which robbers took $4 million in cash, and instead organized for the robbers to be kidnapped and bribed into silence.
The controversy risks derailing his bid for a second term as African National Congress (ANC) president. The panel's findings are due to come just weeks before the deeply divided ruling ANC gathers to elect a leader.
Asked if he was concerned that the panel's findings could put an end to his presidency, he said "no" and told reporters he had faith in South Africa's "democracy and institutions".
Lawmakers in Pretoria will next month debate the findings of a special panel probing whether he should face impeachment over allegations that he covered up a crime.
Asked if he was concerned that the panel's findings could put an end to his presidency, he said "no" and told reporters he had faith in South Africa's "democracy and institutions".
"I have put my case forward, let us leave it to the panel to come up with the outcome," he said as he wrapped up his two-day state visit, the first to be hosted by King Charles III.
"We cannot prejudge it... let's leave it to the panel to report and anything else that flows from that we handle then," he said.
The scandal has stained the image of Ramaphosa, a protege of anti-apartheid icon Nelson Mandela. In 2018 Ramaphosa had been trumpeted as a clean pair of hands after the graft-tainted era of former president Jacob Zuma.
Ramaphosa on Thursday also defended his visit to Britain at a time when South Africa is suffering from the loss of two million jobs caused by the Covid pandemic and rolling power cuts causing misery for citizens.
But he said such visits were vital to promote investment and cooperation opportunities that would have positive benefits for the people of South Africa.
"We had a really great meeting with the prime minister (Rishi Sunak). We put our message across very strongly that we want investment to be upgraded and more and more British companies to invest in our country," he said.
