South Africa's parliament said on Wednesday that President Jacob Zuma will deliver the State of the Nation Address (Sona) as planned on February 8 despite calls from within the ruling party and the opposition for the scandal-plagued leader to step down.

Zuma, 75, has seen a reversal of fortune since deputy president Cyril Ramaphosa succeeded him as African National Congress leader last month.

The party is discussing whether to force him to resign as head of state before his second term ends next year. The opposition has said it wants Zuma to be removed from office before delivering the Sona.
