It is believed the exams were postponed due to pro-democracy protests planned for Tuesday morning.

Eswatini, Africa's last absolute monarchy, has been rocked by waves of protests since June last year as demonstrators call for major constitutional reforms that will allow them to elect their own leaders.

Acting Prime Minister Themba Masuku told a press conference on Monday that the government was not taking lightly threats of mass protest action.

He said protests “have the potential to destroy lives, property and the economy, all of which require utmost protection”.

"There are processes to be followed whenever there are constitutional amendments to be made," Mr Masuku added.
