Sapa reported that the government’s communication and information service said that communications minister Ivy Matsepe-Casaburri would be the acting president from midnight until the new president has been sworn in Thursday.
The new president, expected to be ANC deputy president Kgalema Motlanthe, will be elected at a parliamentary sitting in Cape Town.
Members of the national assembly will meet in the chamber at 11:00 and, following short period for prayers and meditation, Chief Justice Pius Langa will call for nominations of candidates for election as President and thereafter announce the names of the persons duly nominated.
"Depending on the number of valid nominations received, the election is not expected to last more than two hours," said Vuyelwa Qinga-Vika, head of parliament’s media management unit.
Thereafter the President elect, at the invitation of the Speaker, Baleka Mbete, will address the house. The proceedings will then adjourn.
"The swearing in of the President-elect is expected to take place at Tuynhuis in the same afternoon."
The new president is expected to announce the Cabinet and deputy president immediately after being sworn in.
