Malaysia's Mahathir joins calls to oust 'thief' PM

Kuala Lumpur : Former Malaysian leader Mahathir Mohamad called for a sustained push to topple scandal-plagued Prime Minister Najib Razak as thousands rallied on Saturday to demand the premier's resignation over the 1MDB corruption saga.

Malaysians clad in the yellow of the reformist Bersih campaign flooded Kuala Lumpur for the second time in 15 months to vent anger over allegations that billions of dollars were looted from state investment fund 1MDB, Najib's brainchild.

Speaking to a crowd of at least 20,000 under the shadow of the capital's giant Petronas Towers twin skyscrapers, Mahathir, 91, accused Najib of stealing public money and said Malaysia was "controlled by thieves".

"Time has come for us to topple this cruel regime. Najib is no longer suitable to be the prime minister. He is abusing the law," Mahathir said.

Malaysia has been seized since last year by the 1MDB scandal, which has sparked investigations in several countries.

Najib, 63, and 1MDB deny wrongdoing.

But the US Justice Department -- which has filed lawsuits to seize assets it says were purchased with stolen 1MDB money -- says the fund was pillaged in an audacious campaign of fraud and theft that involved an unnamed top Malaysian official.

A Malaysian Cabinet official has since admitted that individual was Najib.

Najib last year abruptly shut down Malaysian investigations, fired the attorney general and purged ruling-party critics. 

Few expect him to be toppled anytime soon.

Najib on Friday condemned Bersih as an opposition plot "to unseat a democratically-elected government".
