KUALA LUMPUR, Malaysia — Mahathir Mohamad has said after he led a Malaysian opposition alliance to a historic election victory that he expects a prime minister will be sworn in within a day.

Mahathir was the country's authoritarian leader for 22 years until 2003. He says the opposition's majority is bigger than announced so far.

The 92-year-old Mahathir says a representative of Malaysia's constitutional monarchy has contacted the opposition to acknowledge its victory.

Mahathir emerged from retirement and joined the opposition after being angered by an epic corruption scandal involving Prime Minister Najib Razak.

The opposition's win ends the National Front's 60 year hold on power.
