The bill was tabled ahead of a general election that is expected to be called within weeks and as Najib faces widespread criticism over the scandal at state fund 1Malaysia Development Berhad (1MDB).

Under the Anti-Fake News 2018 bill, anyone who publishes so-called fake news could face fines of up to 500,000 ringgit ($128,140), up to 10 years in jail, or both.

"The proposed Act seeks to safeguard the public against the proliferation of fake news whilst ensuring the right to freedom of speech and expression under the Federal Constitution is respected," the government said in the bill.

The government defined fake news as "news, information, data and reports which is or are wholly or partly false" and included features, visuals and audio recordings.

The law, which covers digital publications and social media, would apply to offenders outside Malaysia, including foreigners, if Malaysia or a Malaysian citizen were affected.

The government said in the bill it was hoped the public would be more responsible and cautious in sharing news and information.

Opposition lawmakers have questioned the need for such a law, arguing that the government already had broad powers over free speech and the media.

"This is an attack on the press and an attempt to instil fear among the rakyat (people) before GE14," opposition lawmaker Ong Kian Ming said on Twitter after the bill was tabled, using a Malaysian term for this year's election.

Parliament, where the government has a comfortable majority, is expected to vote on the bill this week.

U.S. President Donald Trump popularised the term "fake news", which he used to describe media reports and organisations critical of him.

The term quickly became part of the standard repertoire of leaders in authoritarian countries such as Venezuela and Myanmar.

Governments elsewhere in Southeast Asia, including Singapore and the Philippines, have also proposed laws aimed at clamping down on the spread of "fake news", to the dismay of media rights advocates.

UNQUESTIONABLE POWER

A Malaysian press group warned that the proposed bill could stifle the media, as it would give the government full control to remove articles deemed prejudicial to public order or national security.

"To allow one party to have unquestionable power to remove articles it disagrees with could easy (sic) be abused," the National Union of Journalists said in a statement.

The 1MDB scandal, exposed by foreign media and news blogs in 2015, refuses to die down despite Najib's consistent denials of any wrongdoing and his government's firm grip on Malaysia's state-owned mainstream media.

Transactions related to 1MDB are under investigation in six countries including the United States, where the Department of Justice has launched civil cases to recover assets linked to the fund after investigations under an anti-kleptocracy initiative.

The Malaysian government has acted harshly against media reporting on 1MDB. It suspended one newspaper, The Edge, in 2015 and blocked websites for publishing stories critical of Najib's role.

A deputy minister was quoted in Malaysian media last week as saying that any news on 1MDB that had not been verified by the government was "fake".
