A high-level meeting is scheduled for today between the National Assembly Speaker Baleka Mbete and the DA chief whip.
This follows the suspension of DA MP Mike Waters for calling Health Minister Manto Tshabalala-Msimang a thief in parliament last week.
The DA's chief whip Ian Davidson will meet with Mbete to register his party's protest at Waters' suspension for five days.
Waters accused Mbete of "covering up for a thief" by banning a parliamentary question about the minister's Botswana conviction. Mbete had ruled that Waters' question was out of order, stating it contravened section 63 which barred MPs from using "offensive or unbecoming language".
She then evicted him from the National Assembly chamber.
Waters had wanted to know whether, in light of recent media allegations, Tshabalala-Msimang had been convicted of theft in 1976 and whether she had disclosed this information to President Thabo Mbeki when he appointed her.
Yesterday Davidson said Mbete's job was to ensure parliament "carried out its oversight responsibilities properly".
