Who is Cyril Ramaphosa?
As the South African president's future could be uncertain, we're taking a look at what we know about Cyril Ramaphosa.
The 71-year-old was elected in 2018, some 25 years after he first revealed his ambitions to become president.
He joined the African National Congress (ANC) party after experiencing the injustices of the racist apartheid system from a young age.
At university he became involved in the black consciousness movement and spent months in solitary confinement as a result.
In the 1980s he led the National Union of Mineworkers (NUM) in one of the largest strikes in South Africa's history, pushing back against white mine bosses.
Later he helped Nelson Mandela to negotiate an end to apartheid.
Mr Ramaphosa had hoped to become Mr Mandela's deputy president after this, but he was overlooked in favour of Thabo Mbeki.
Instead he took up a role as an MP and played a leading part in drafting South Africa's post-apartheid constitution.
For a time he withdrew from politics to become a business executive, and he had lucrative ventures in sectors including telecoms, the media, beverages, fast food and mining.
By 2015, he had become one of South Africa's wealthiest politicians.
However he faced a major blow to his reputation when police killed 34 workers at the Marikana platinum mine (which was owned by a company Mr Ramaphosa was a director of).
Emails emerged showing he had called for action against the miners for engaging in "dastardly criminal acts", which appeared to be a reference to their violent strike.
He was later cleared of involvement in the killings by an inquiry.
Two years later, he became deputy president to Jacob Zuma.
As Mr Zuma's two-term limit approached, Mr Ramaphosa battled it out for the top job with the president's ex-wife Nkosazana Dlamini-Zuma.
He beat her to become ANC leader in December 2017, and eventually took on the role as president when Mr Zuma was pressured to step down the following year.
Mr Ramaphosa inherited a difficult situation from his predecessor, and has faced scandals during his time as president - but survived to be re-elected to the helm in 2022.
Since then he has struggled to lift economic growth and make a dent in high unemployment as a third of South Africans remain jobless.
