Government officials implicated in the awarding of fraudulent contracts for state funerals remain in their posts, months after an investigation recommended action be taken against them.

MPs were shocked to hear from public works and infrastructure minister Patricia de Lille that the department's most senior official, director-general Sam Vukela, who had been fielding their questions and explaining why no action had been taken, was also implicated.

The department of public works and infrastructure was appearing before parliament's public accounts committee (Scopa) to account for matters raised by the auditor-general in the 2018/2019 annual report.

DA MP Benedicta van Minnen asked about action taken regarding fraudulent contracts, where prices were inflated and payment irregularities found for the state-sponsored funerals of late stalwarts Winnie Madikizela-Mandela, Zola Skweyiya and ambassador Billy Modise.

The three funerals cost taxpayers a whopping R76m, with the department spending, among other amounts, R7m to hire padded chairs, leather couches and scatter cushions, R2,47m for draping, R470,000 for serviettes and R695,000 for orchestra equipment for Madikizela-Mandela and Skweyiya's funerals.

In some instances, the service provider allegedly supplied items that the department had not requested.

Vukela, according to De Lille, was one of the officials who have been implicated in a forensic investigation report by PricewaterhouseCoopers (PwC) on the fraudulent contract management.

Vukela told MPs he was not aware he was implicated.

The deputy director-general responsible for governance and risk, Imtiaz Fazel, told MPs the procurement processes for those three official funerals were fundamentally flawed and that created a platform for "major" transgressions.

He said the over-payment by the department was due to officials approving invoices without applying the necessary application to ensure they were valid and accurate.

The over-payment resulted in fruitless and irregular expenditure. He said an investigation by PwC found this happened due to negligence on the part of individuals and management involved in overseeing the funerals in question.

He said there was concealment of further commissions in the invoices which were not detected and inflation of invoices by at least 15% beyond the invoice price.

The investigation found this was due to negligence by the officials concerned.

Fazel added: "The investigation concluded that the officials who approved the invoices did not conduct the necessary diligence and oversight and calculations to ensure that we were charged for services actually rendered..."

He said the investigation report was approved by De Lille and that at least four individuals in the department should be charged for various transgressions. When Scopa chairperson Mkhuleko Hlengwa asked for the names of the implicated officials, Fazel read out four names, but did not mention Vukela.

After almost an hour of discussions, De Lille dropped a bombshell, telling MPs her officials had not been completely honest and that the DG (Vukela) was also implicated.
