Prime Minister Dr Mahathir Mohamad wants the mastermind behind the sex video implicating Economic Affairs Minister Azmin Ali to be punished.

"If we can find them and identify those who actually produced this particular video and show it on the net, I think they should be punished.

"This is not the kind of politics that we want," he told reporters in Kuala Lumpur this afternoon.

Mahathir also denied that he was defending Azmin when dismissing the sex video as fake even before the authorities completed their investigations.
