Western Cape Premier Helen Zille says internal investigations in the City of Cape Town will determine who faces the music over the Integrated Rapid Transit system bungle.

Zille said the drastic escalation of costs for the project which has ballooned to almost triple the initial R1.3-billion was deliberately kept from her and other senior officials.

Zille said although one senior member of the project management team was identified, she had not ruled out the possibility more officials could face disciplinary action.

"Well I will let the process identify who needs to be taken through a disciplinary procedure and that is exactly what we're underway with at the moment. That is an internal investigation as far as I understand, but there will be proper disciplinary procedures with independent adjudication of those procedures."

The senior official would not be identified at this stage, Zille said.

ID to investigate IRT bungle

At the same time, the Independent Democrats said it would conduct its own investigation into the IRT's bungled finances.

The ID's Rodney Lentit said the DA was proving how poorly it was running the city.

"Officials are there to do their work, but politicians in the city of Cape Town it is their work to do an oversight role and here I blame the Mayor of the city of Cape Town and the MAYCO (Mayoral Committee) member who is responsible for this portfolio."
