Cape Town - EFF spokesperson Mbuyiseni Ndlozi told President Jacob Zuma to leave the National Assembly, ahead of his State of the Nation Address on Thursday.
"Please leave, baba. Mr Zuma, please leave. You are a constitutional delinquent,” he said.
Zuma was meant to have started his speech at 19:00, but nearly an hour of points of order and interjections delayed proceedings.
Cope president Mosiuoa Lekota said: "The gentleman before you has broken his oath of office. He's admitted that.
"He can't be a member of Parliament when he's discharged himself. In English he's called a scoundrel."
Speaker Baleka Mbete, who had her hands full trying to maintain order, said what Lekota was saying was not a point of order.
Lekota then raised his voice and Mbete again interrupted. She repeatedly told various politicians what they were saying were not points of order.
After Cope MP Willie Madisha raised a point of order, he was told to leave the House, and Parliament’s protection services were called to escort him out.
