South Africa’s electoral commission said it had barred former president Jacob Zuma from standing in the May 29 general election.
“In the case of former president Zuma, yes, we did receive an objection, which has been upheld,” commission president Mosotho Moepya told reporters, without giving details, AFP reports.
“The party that has nominated him has been informed” as have those objecting to the move, he added.
The decision can be appealed if lodged before April 2.
Zuma, 81, was forced out of office in 2018 under a cloud of corruption allegations.
He is campaigning for the opposition Mkhonto we Sizwe party in an attempt to relaunch his career and weaken his former party, the ruling African National Congress.
The general election, after which the victor will appoint a president, is set to be tense.
