The address was scheduled for 8 February.
However, Mbete says it had become clear that it was unlikely that a joint sitting of the two houses would be uneventful if it was held this Thursday as planned.
She adds that Parliament took into account views of political stakeholders, society and concerns in the political environment.
Mbete says that as Parliament was preparing to write to President Jacob Zuma to request the postponement of his address, he was already doing the same.
Standing on the steps of Parliament, Mbete says a new date will be set as soon as possible.
She says it’s hoped that the address will not be postponed for more than a week, so as not to affect the tabling of the Budget.
Meanwhile, former ANCYL and ANC NEC member Pule Mabe has been appointed the national spokesperson for the ANC.
This was confirmed by the ruling party today, reports Sydney Morweng-news editor.
“As the ANC we wish Cde Mabe well in his new role and has full confidence in him to execute his new task at the helm of our communication machinery with distinction,” read ANC’s media statement.
