JOHANNESBURG (Reuters) - South Africa’s former Home Affairs Minister Malusi Gigaba has quit as a member of parliament following his resignation from the government after the High Court found he had lied under oath, parliament said on Thursday.

Gigaba resigned as minister on Tuesday in a case involving efforts to set up an immigration facility for wealthy VIPs at an airport.

The speaker of parliament, Baleka Mbete, received a letter from Gigaba informing her of his resignation, parliament said in a statement without providing further detail.

Last month, South Africa’s anti-graft watchdog said Gigaba should be disciplined for lying about the wealthy Oppenheimer family’s attempt to open the private immigration facility.

Gigaba, who was finance minister in 2017-2018, has denied any wrongdoing. Last month he apologized over a private sex video that was leaked.
