In his weekly newsletter released on Monday, a day before the planned protests on June 30, Ramaphosa acknowledged that many South Africans have genuine concerns about illegal immigration, weak border controls, pressure on public services and criminal networks exploiting the country’s immigration system.

“These concerns are real and they deserve to be heard,” Ramaphosa said.

However, he stressed that public frustration must not be used to justify lawlessness.
