Mahathir Mohamad has been sworn in as prime minister of Malaysia again after a shock election victory, 15 years after he stood down.
Supporters waved flags and cheered outside the Istana Negara palace in Kuala Lumpur as took the oath inside, reports BBC.
The man who governed for more than two decades has become, at the age of 92, the world's oldest elected leader.
He came out of retirement and defected to the opposition to take on and beat former protégé Najib Razak.
His historic win ousted the Barisan Nasional (BN) coalition, which has been in power since independence in 1957.
