Malaysia has unveiled a five-year plan to clamp down on corruption in government, months after a multibillion-dollar corruption scandal brought down the previous administration.

The plan, launched by Prime Minister Mahathir Mohamad, will involve sweeping changes to the appointment process for key positions, require legislators and ministers to publicly declare their assets, and introduce new laws to regulate political funding and lobbying.

Voters rejected Mahathir’s predecessor Mr Najib Razak in an election in May last year, amid widespread public disgust over allegations that about four point five billion dollars has been stolen from 1MDB, a State fund set up by the former Prime Minister.

Mr Najib, his wife and several high-ranking officials of his former administration are now facing criminal charges related to 1MDB and other government entities. All of them have pleaded not guilty.
