Corruption Watch 'will not be investigating Guptas'

This is mainly due to limited resources but also because there are other investigations into the Guptas.

JOHANNESBURG - Corruption Watch says it will not be investigating the Gupta family, mainly due to limited resources but also because there are three other investigations.

The African National Congress (ANC), the Hawks and the Public Protector will be investigating whether President Jacob Zuma's relationship with the family has started a process of 'state capture'.

It comes after Deputy Finance Minister Mcebisi Jonas revealed he was offered the finance minister's job last year, by the Gupta family.

Corruption Watch says Zuma may be guilty of corruption if he is found to be abusing the appointment of ministers to benefit business interests.

However, the organisation's David Lewis says they're not launching their own investigation at this stage.

"We're very interested in this and we'll watch it very closely."

Lewis says there could be serious implications for Zuma, but this will be determined by the outcome of three separate investigations that are underway.
