Johannesburg - Former National Treasury director-general Lungisa Fuzile has concluded his testimony at the Zondo commission which largely corroborated evidence provided by former finance ministers Nhlanhla Nene and Pravin Gordhan.
Fuzile focused his testimony on Monday on the controversial nuclear deal that was championed by former president Jacob Zuma.
He told the commission that Cabinet approved the deal despite advice from Nene and Treasury officials.
He said if the deal had gone ahead it would have had devastating effects on the country.
"This was the biggest procurement ever in the history of the country, yet the processes were rushed and some of the stuff that was talked about was not followed. If nuclear had proceeded, this country would have been in trouble. The process that was followed was seriously flawed. There was a brushing aside of the true cost of the project," said Fuzile.
