Reuben Brigety, the US ambassador to South Africa, said he will resign effective January 10 in line with procedure after Donald Trump's election victory.

Brigety commented in a statement on Monday.

He said this was "in accordance with standard procedure during a change of presidential administration".

Last year, Brigety made headlines when he alleged that weapons were loaded onto a Russian ship between South Africa and Washington.

An investigative panel appointed by President Cyril Ramaphosa found no evidence to substantiate Brigety's claims.
