Ex-Malaysian Prime Minister Najib Razak has been banned from leaving the country, immigration officials say.
This comes after Mr Najib said that he and his wife were planning to go on an overseas holiday on Saturday.
Earlier this week, Mr Najib’s long-ruling Barisan Nasional coalition suffered a shock electoral defeat.
Mr Najib has been accused of diverting $700m (£517m) from a state investment fund in 2015, but has since been cleared by the authorities.
On Thursday, Mahathir Mohamad was sworn in as Malaysia’s new prime minister, becoming the world’s oldest elected leader at 92.
He has said there will be a thorough investigation into cases of alleged corruption including the one involving the state investment fund.
