South Africa’s President Cyril Ramaphosa is due to appear on Wednesday morning before the country's long running corruption inquiry.

It was set up to investigate allegations that his predecessor Jacob Zuma – during his term in office – allowed the wealthy Gupta family to plunder state resources and to influence policy and cabinet appointments.

Both Zuma and the Guptas deny any wrongdoing.

The corruption is estimated to have cost South Africa $81bn (£58bn) in public funds and lost opportunities.

Mr Ramaphosa was a deputy leader of the governing ANC party at the time.

He has been called to answer questions on what the party knew, if anything, about the alleged misconduct and if they did anything to try to stop it.
