President Cyril Ramaphosa is expected to deliver the address at Cape Town City Hall on Thursday.

Ramaphosa's speech comes as the country continues to battle continuous power cuts, high unemployment rate, crime and a myriad of other issues. 

There are high expectations from civil society organisations, business sector and ordinary citizens.

The EFF have vowed to prevent Ramaphosa from speaking until he provides answers on the theft of foreign currency from his Phala Phala farm in 2020.

But Mapisa-Nqakula said she is not concerned by the threats. 

"I have heard about the threats; it remains to be proven.

"As far as we are concerned this is a very unique opportunity for the arms of state to be under the same roof and for the president to address the nation.

"It is a once-off occasion where the president takes the nation through the entire programme of the government.

"So, I plead with South Africans to have an appreciation of what the State of the Nation Address is about, "says Mapisa-Nqakula.

She added: I am not having sleepless nights. We have rules and we have all taken oath, so we have to obey the laws of the republic but also to allow the presiding officers to provide guidance including the rulings.

"So, I do not want to entertain this notion of people who are threatening to disrupt the State of the Nation Address. The State of the Nation Address will proceed, and I can assure you it will be successful." 

She declared herself satisfied with the preparations, including the security measures put in place.

"We are happy with what we have seen. We are happy with arrangements which have been made by the team from Parliament, together with the team from the department of public works, and the security cluster.

"We are also happy with security measures which have been put in place. We are also happy with the seating arrangements; I think the manner in which seat allocation has been done is a true reflection of the representation of different constituencies."
