African National Congress Youth League president Julius Malema called on young people to purge the "apartheid agents" from the Tshwane Metro Council.
Malema addressed a crowd of about 2 000 supporters at an election rally north of Pretoria.
"The youth must work to get rid of these administrators we have inherited," said Malema to applause from the crowd.
"These people occupied administrative positions in the old Pretoria council; now they have the same job in Tshwane."
Before he arrived - more than two hours late - Malema's supporters kept themselves busy by singing songs about ANC president Jacob Zuma, soldiers and machine guns.
Malema laid into, among others, MECs, the DA Youth, the Congress of the People, the black middle class and corrupt politicians.
He said the party was seeking 70 percent of the vote.
Malema said being the youth league of the ruling party gave the league the right to lead all the youth in South Africa, "including the children of Helen Zille".
He said young people must admire educated people, not criminals.
"You must never role model a rich person who can't explain how they got rich. In the ANC we must not have corrupt people as role models. Corrupt means a simple thing - you can't explain the big amount in your bank account.
"In less than a year you have got everything. Yesterday you were down and out, but today you have everything which shows in your fancy dress code.
"We were drinking with you on the corner, COPE, but now you walk tall. You claim to be men of the suburbs, but you are products of the squatter camps," he said.
Malema accused the black middle class of forgetting their roots and betraying the party.
"The black middle class say we don't care about them, but we (the ANC) produced them, we opened the gates to the suburbs.
"They can't vote against the ANC - affirmative action and black economic empowerment are ANC policies," he said.
Malema encouraged MECs to adopt poor township families.
"They have too much money and don't know what to do with it, so they end up spending it on expensive alcohol. But they must spend that money on the poor.
"They build big houses, but their neighbours have got no water," he said.
