This comes after Floyd Shivambu’s surprise exit from the red berets to join former President Jacob Zuma’s uMkhonto weSizwe Party.
EFF leader Julius Malema had warned that Shivambu loyalists might follow him, but Dlamini said so far this has not been the case.
“The leadership is currently in the province to gather feedback on the party’s decline in election performance,” he said.
“We run this organisation by trying to get to the scientific evidence and information, not through assumptions. There is no assumption or anything, we want to listen to the branches to figure out what went wrong.
“They are the ones who were on the ground doing door to door campaigns and they were at the voting stations so they will be able to tell us what happened on our side.
“By Monday we will have a clear response and a clear diagnosis and a factual information of what really transpired” said Dlamini.
Meanwhile, the EFF and other parties were challenged by the MK Party, which is led by Zuma.
Zuma is an important figure in KZN politics and was instrumental in the ANC winning the province back from the Inkatha Freedom Party (IFP) in the early 90s.
The MK party received a majority of votes in KZN, replacing the IFP and the ANC as the biggest parties in the province.
The ANC also embarked on a fact-finding mission in KZN a few days ago.
The party’s national executive committee (NEC) met with the provincial leadership and regions to establish what problems the party faced before the elections.
The ANC is currently in a government of provincial unity with the IFP and the Democratic Alliance (DA) in KZN, despite having performed poorly in the provincial elections.
