Incumbent Finance Minister Malusi Gigaba, appears to have acted irregularly to award the rich controversial Gupta family citizenship, when he was in charge of home affairs.

According to letters released by the Economic Freedom Fighters (EFF) there was a fast-track granting of citizenship highly suspicious to the family and the party says it will go to court to have the Guptas’ citizenship revoked.

One of the letters released by the EFF, which appears to bear Gigaba’s signature, is dated May 30 2015. It purports to show Gigaba writing to Ajay Gupta to tell him that the family’s representations had resulted in their application for citizenship being successful.

“I have decided by the virtue of the powers vested in me under the South African Citizenship Amendments Act to waive the residential requirements in regards to your application for naturalisation and grant you early naturalisation,” Gigaba allegedly wrote.

Five months earlier before Gigaba took charge of home affairs, the then director-general of Home Affairs, GG Hlatshwayo, had written to the family refusing their application on the grounds that they had not lived in South Africa for the required five years.

The correspondence followed an application for citizenship in 2013 from Ajay Gupta; his wife, Shivani; his mother, Angoori and their two sons, Kamal and Surya Singhala.

Mbuyiseni Ndlozi EFF spokesman said:

“This is proof that the Guptas are not attempting to capture the state but have already captured it – and all its leaders. This shows that everyone is already dancing to their tune.”

Varun Gupta received his naturalised citizenship papers seven months after his uncle and aunt.
