The blank space next to the title of “president” on the ANC Youth League’s website was replaced with expelled leader Julius Malema’s name by Wednesday afternoon.
Earlier, the website page listing the national executive committee of the ANCYL on www.ancyl.org.za had blank spaces next to the positions of “president” and “secretary-general”.
Suspended secretary general Sindiso Magaqa’s name had also been added.
Although Malema was expelled from the ANC last week following an announcement by the party’s national disciplinary committee of appeal, the ANCYL has insisted that he will remain president until its next election in 2014.
ANCYL spokeswoman Magdalene Moonsamy said they were shocked their website had been "tampered with".
"Such tampering is condemned and we hope that there will be no future repetition of such interference as information of the ANCYL belongs to the ANCYL and not individuals who believe otherwise," she said in a statement.
"We do expect that such wrongdoings will never be repeated by those who advance a malicious agenda. All information has been restored and the website has returned to its original state."
