Former MK head of intelligence Ronnie Kasrils.
The ANC has wished former minister Ronnie Kasrils luck in his campaign for spoilt votes, the Sunday Independent reports.
"We are out here campaigning for people to vote for the ANC," secretary general Gwede Mantashe was quoted as saying.
"If he is campaigning for the spoiling of votes, all I can do is wish him luck."
Kasrils and former deputy health minister Nozizwe Madlala-Routledge have reportedly asked South Africans to take a stand against fraud and corruption by spoiling their votes.
The two are garnering support for the "Sidikiwe Vukani! [We are fed up! Wake up!] Vote No" campaign, due to be launched at Wits University on Tuesday, the newspaper reported.
The aim of the campaign was to persuade activists and others not to vote for the African National Congress, or at least spoil their vote, on May 7.
A statement by the campaign issued last week said: "A one-time minister and a deputy minister in ANC governments are among a group of former anti-apartheid activists who are backing a campaign calling on voters to come out and vote by either spoiling their ballots or to voting tactically in protest against corruption and current government policies."
"The ANC needs to know that it can no longer take for granted its traditional support and we would be failing South Africa and our democracy by not voting," said the statement.
Former home affairs director general Mavuso Msimang has distanced himself from the campaign.
"Whatever deficiencies that exist within the ANC should be fixed," Msimang was quoted as saying.
He has been critical of the ruling party and recently wrote that "there is a crisis within the ANC". – Sapa
