JOHANNESBURG - Acting Police Minister Firoz Cachalia says law enforcement agencies are prepared for any eventuality on 30 June.
A large-scale police deployment is underway across the country, with security operations being intensified in all provinces from this week.

Anti-illegal immigration groups have given undocumented foreign nationals until the end of June to leave the country.
They have also issued an ultimatum to government to present a plan to address illegal immigration by then.
"I am satisfied that the police are ready to deploy across the country," says Cachalia.
"We will be engaging with all provincial Premiers, mayors, metro police, the private security industry to ensure that we have the resources in place to deal with any eventuality," he adds.
The acting minister said authorities are concerned that rogue elements within protest movements could escalate demonstrations into civil unrest.
Cachalia said that while people have the constitutional right to protest, there remains a risk of violent confrontation.
"I am under no illusion that there are some forces that are involved in this kind of mobilisation," he says.
"That concerns me because the police have the right to protect the right to protest, but they also have to deal with criminality," he said.
