IEC Chief Electoral Officer, Mosotho Moepya, explains the conditions under which a ballot can be considered spoilt. Watch. Smaller parties
In the run-up to this year's elections, former intelligence minister Ronnie Kasrils
and former deputy health minister Nozizwe Madlala-Routledge
led a campaign supporting spoilt votes.
They launched the "Sidikiwe! Vukani! Vote No" campaign in April and called on South Africans to either vote for a minority party, or spoil their ballots.
The campaign was aimed at convincing struggle activists and others not to vote for the African National Congress.
They said this tactical move would help deepen democracy through diminishing the ANC's majority.
The two had previously said they were against corruption and the lavish lifestyles of ANC members.
Before the election, Kasrils said ordinary people were suffering because taxpayers' money was being spent on upgrades to President Jacob Zuma
's private home in KwaZulu-Natal and travel arrangements for the wealthy Gupta family, who reportedly had close ties with Zuma.
However, the City Press on Thursday reported that Kasrils did not spoil his vote.
"I voted for two parties, nationally and provincially, but not the ANC or the DA," he was quoted as saying.
"...I want to see some smaller parties entering the provincial or the national [government] and speaking up against corruption, for better government, for service to the people and for accountability."
Kasrils believed that supporting two smaller parties would provide the change he wanted to see in the country.
