More senior officials in the African National congress have openly come out in support of Deputy President Cyril Ramaphosa in the contest to succeed President Jacob Zuma at the helm. 

While voting continued Monday, party's spokesperson, Zizi Kodwa, used twitter to express support for Ramaphosa to lead the ANC. He is contesting for the top party job against Nkosazana Dlamini-Zuma, the former chairperson of the African Union Commission.

ANC chief whip Jackson Mthembu, who has previously stated his support for Ramaphosa, also used twitter on Monday to reiterate his stance.

"Voted for Ramaphosa and other five incorruptible leaders [at the ANC] conference. My vote is to save the ANC and my country. We must," Mthembu said.

"The ANC 54th conference must restore the integrity of our movement. It must also restore the confidence of our people in the ANC through a capable leadership. I am confident that the ANC conference will start the process to save our movement from state capture corruption. Yes it must!"

Kodwa said that Ramaphosa would "inspire hope" for the party.

"Am casting my vote for comrade Ramaphosa for ANC president, whatever happens I trust he will restore confidence and inspire hope. It is early hours but it's worth waiting," Kodwa tweeted.

"My last media briefing as the ANC spokesperson with ANC secretary general, Gwede Mantashe now 10:00. It's been a life experience to work with him."

This comes as ANC delegates voted overnight and continued on Monday morning to cast their votes for the party's top six officials who were nominated on Sunday evening. 

Ramaphosa and Nkosazana Dlamini-Zuma emerged as the only two candidates vying for president of the ANC 

Rampaphosa, the deputy president of the republic, received 1,469 nominations from six provinces for president while Dlamini-Zuma, a former cabinet minister and African Union Commission chairwoman, received 1,094 nominations, according to election officials.
