New revelations of senior government officials benefiting from the arms deal has placed the credibility of the joint investigating team in the dock, said the Democratic Alliance on Thursday.

Reacting to an article in this week's Financial Mail, the DA's former public accounts spokesperson, Raenette Taljaard, said: "The price of a cover-up is always that information will continue to leak and do damage to both the government and those responsible for a weak and flawed investigation."

According to the magazine, the late former minister defence Joe Modise, Denel chairperson Ian Deetlefs and Armscor chairperson Ron Haywood received shares worth millions through a company they hoped would benefit from offsets linked to the arms deal.
