JOHANNESBURG - National Assembly Speaker, Baleka Mbete, says an investigation is underway to determine who cut the Parliamentary television feed when chaos erupted in the house on Thursday.

The dedicated Parliamentary channel was cut when a sitting of the National Assembly descended into chaos.

Mbete denies she's the one who ordered a temporary blackout of the channel.

Mbete again lost control of the house on Thursday night when opposition parties clashed during the debate on the Nkandla committee's report.

Chaos ensued after she tried to block debate around Nkandla, which had apparently been agreed to by the chief whips of parties in Parliament.

The committee found President Jacob Zuma is not responsible for the overspending on upgrades on his Nkandla home.

During the debate an EFF MP who refused to withdraw her remarks that Zuma was a thief and a criminal, was hauled out of the chamber by police.

Mbete says it was unclear who decided to interfere with the broadcast of the session.

The Democratic Alliance (DA) has again called for Mbete to be removed as speaker of the National Assembly.

DA Parliamentary leader Mmusi Maimane has accused Mbete of failing to do her job.

"Baleka Mbete has consistently favoured the African National Congress (ANC) over opposition Members of Parliament (MPs) and is clearly executing Luthuli House's agenda."

The party believes she has destroyed her credibility.

The DA's John Steenhuisen says, "She started to try and shut down the opposition. She abused her position."

The party has also strongly objected to the use of riot police in Parliament.

Opposition MPs claim police assaulted several politicians.

It has written to Deputy President Cyril Ramaphosa, asking him to ensure that they never be allowed to be in the chamber.
