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 (NEC) 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.
It was reported on Wednesday morning that Malema and Magaqa's names had been removed from the website, but ANCYL spokeswoman Magdalene Moonsamy denied knowledge of this.
“We do not know who tampered with the website,” Moonsamy told the New Age newspaper.
Suspended youth league spokesman Floyd Shivambu's name also remained on the list of NEC members.
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.
He was found guilty of sowing division in the party and of bringing it into disrepute for unfavourably comparing the leadership style of President Jacob Zuma to that of former president Thabo Mbeki, and for remarks on bringing about regime change in Botswana.
Magaqa was suspended for a year for making derogatory remarks about Public Enterprises Minister Malusi Gigaba. He has since apologised.
Shivambu's ANC membership was suspended for three years for swearing at a journalist and for issuing a statement calling for a change of government in Botswana. - Sapa
