South Africa's Cyril Ramaphosa abandons May Day rally after booing

South Africa's President Cyril Ramaphosa had to leave a May Day rally after workers stormed the stage where he was speaking.

Chanting "Cyril must go," they held up signs demanding a wage increase during a ceremony in a stadium near the north-western city of Rustenburg.

The protesters, who worked at a local mine, have been striking for weeks.

President Ramaphosa tried to address the miners' concerns but was greeted by booing.

The workers want an annual salary pay rise of 1,000 rand ($63; £50) - a demand which President Ramaphosa addressed directly.
