Prime minister Dr Mahathir Mohamad is mulling a cabinet reshuffle following the opposition's massive victory at the Tanjung Piai by-election last weekend.

Speaking at a press conference at the Bersatu headquarters in Petaling Jaya, Mahathir said the issue of a reshuffle was raised during the party's supreme council meeting this afternoon during which they discussed the by-election.

Without committing to any time frame, Mahathir did not discount the possibility that the reshuffle might take place before the Asia-Pacific Economic Cooperation (Apec) summit to be hosted by Malaysia in November next year.
