CAPE TOWN - Democratic Alliance (DA) leader Helen Zille says opposition parties can't win the battle against a "corrupt government" by destroying Parliament and breaking the rules.

Zille led a rally outside the national legislature a day before the State of the Nation Address (Sona).

The Economic Freedom Fighters (EFF) have threatened to interrupt the president's speech to ask him when he intends repaying part of the public money spent on upgrades to his private home in Nkandla.

According to Zille, EFF Members of Parliament (MPs) are going about things the wrong way.

"We can win against the ANC by using the institutions and not by destroying them. So we must win by playing by the rules."

Earlier today, hundreds of Parliamentary employees affiliated with the National Education, Health and Allied Workers Union (Nehawu) threatened to withhold their services if they were not granted a thirteenth cheque, among other demands.

Parliament's presiding officers have refused to speculate on what steps will be taken should EFF MPs disrupt proceedings inside the chamber.

There could be a volatile showdown on Thursday if EFF leader Julius Malema makes good on his threat to disrupt the president's speech.

The employees say they won't help with preparations for the president's Sona unless this is granted.
