Kuala Lumpur, March 29 (IANS): Malaysia's opposition coalition staged a rally in capital Kuala Lumpur to press demand for Prime Minister Najib Razak's resignation over his alleged involvement in corruption and financial mismanagement.

The public rally on Monday night was organised by the "Save Malaysia" movement, formed after an investigation revealed in July 2015 that Najib was allegedly involved in mismanagement at the debt-laden state fund 1Malaysia Development Berhad (1MDB), chaired by himself, and about $681 million were deposited into his personal bank account, EFE news reported.

Several hundred people as well as former premier Mahathir Mohamad participated in the rally.

Mohamad last week filed a lawsuit against Najib over "abuse of power" and accused him of trying to obstruct investigations into the case.

Najib, who is also the finance minister, took the chair of the advisory board of 1MDB which, between 2009 and 2014, accumulated a debt of 42 billion ringgit (about $11 billion).
