South African Citadel Group moves to allay Panama Paper fears, Buhari to expose beneficial owners of companies

Citadel Group said on Friday that, if any of its clients are mentioned in the Panama Papers, its services to them have always been tax compliant.

"We can assure you that the services provided to our clients have, to our knowledge, always been regulatory and tax compliant. Citadel will not compromise on governance standards," the company said in a statement.

It was outlining its dealings with Panama-based Mossack Fonseca, the law firm from which 11.5m confidential documents were leaked.
