Protesters hold up a placard during a Bersih rally as protestors call for the resignation of Prime Minister Najib Razak on August 30, 2015 in Kuala Lumpur, Malaysia.

Malaysia's mammoth civil disobedience campaign has heightened pressure on scandal-ridden Prime Minister Najib Razak but is an imminent departure on the cards? Unlikely, analysts say.

The 61-year-old leader, who is no stranger to controversy, has most recently been accused of pocketing almost $700 million from troubled government fund 1Malaysia Development Berhad (1MDB). Najib says the allegations are part of a malicious campaign to force him from office, while his cabinet ministers claim the funds were campaign donations from unnamed sources in the Middle East.
