KUALA LUMPUR (AFP) - Former Malaysia premier Mahathir Mohamad's son has resigned as chairman of the Sepang International Circuit (SIC), which hosts MotoGP and Formula One races, an official said on Thursday (Oct 13).
Mr Mokhzani Mahathir, who had held the position since 2003, vacated the post on October 10 citing "personal reasons", the circuit's CEO Razlan Razali said.
However, Mr Mokhzani - who has also resigned from the board of directors - claimed he was asked to leave, reported the New Straits Times.
Mr Mokhzani declined to comment on the issue when contacted by Agence France-Presse.
In a SIC statement to the media, Mr Mokhzani said it had been an "honour and privilege to be part of the SIC team".
Mr Mokhzani's father, Dr Mahathir, who still casts a long shadow in domestic politics, has been driving the push to oust scandal-tainted Prime Minister Najib Razak.
Mr Najib faces allegations that billions of dollars were plundered from a state-owned investment fund he founded.
Mr Najib and the state investment fund 1Malaysia Development Berhad (1MDB) deny any wrongdoing.
Dr Mahathir, who was the premier for 22 years, quit the ruling United Malays National Organisation (UMNO) in February, saying it had degenerated into an organisation whose sole purpose was to protect Mr Najib.
Dr Mahathir and Mr Muhyiddin Yassin, who was sacked as deputy prime minister by Mr Najib last year, have recently formed a new political party to challenge the premier.
