The Presidency yesterday said Eskom has had to blacklist most of its service providers and suppliers due to illegal activity and corruption, reports EWN.

The Presidency was briefing Parliament's Standing Committee on Public Accounts, on investigative reports by the Special Investigating Unit (SIU).

According to the Presidency, the SIU issued a total of 162 reports to the President on investigations into affairs and procurement at several departments and entities since 2001.

The Presidency said most of the investigations by the SIU that were proclaimed by the President almost always involved infrastructure.

Deputy director general in the Presidency, Matsieti Mekoa, said state-owned enterprises make up just 7% of referrals but have higher financial implications.

Eskom and Transnet also top the list of referrals for blacklisting suppliers.

Eskom is leading the pack with 71 suppliers blocked, followed by the Free State provincial Treasury Department with 56 suppliers restricted, Transnet 51 and Umngeni Water Board 49.

Minister in the Presidency Mondli Gungubele also promised action against those implicated in the probes.
