There has also been focus on the State Security Agency's (SSA) involvement this year, after Parliament asked the agency to vet guests, and also following the now infamous incident at the 2015 SONA when a signal jammer was discovered in the media bay.READ: Scrap Zuma's SONA speech - EFFNo SONA dinnerMgidlana promised that members of the SSA, like members of the SA National Defence Force, police, and the Department of International Relations and Co-operation would only be there in their regular capacities."We are not sure where the rumours are coming from, but it is not coming from Parliament," he said."You and your colleagues will be free to do your work."He guaranteed freedom of movement for journalists in and around the precinct.Mgidlana did not want to comment on the possibility of disruptions during Zuma's speech, saying Parliament was hoping to host a successful event.He also said there would be no SONA dinner this year, as part of government's cost cutting measures.The budget for the event is set at R4m, down from R4.5m last year.
