Thousands of anti-government protesters are likely to gather in Kuala Lumpur on Saturday, to demand the resignation of Malaysian Prime Minister Najib Razak, who has been accused of corruption and siphoning millions of dollars into his private account. 

The Coalition for Clean and Fair Elections, also referred to as Bersih, has estimated nearly two lakh people to turn up for the protests over the weekend, as per reports. 

However, the government has already begun clamping down on the group, blocking their website on Friday citing "national stability", Reuters reported. 

The Malaysian Communications and Multimedia Commission (MCMC) has also sent out a strong warning to anyone who shares messages about the protest on social media. 

"MCMC would like to remind the people to be careful in sharing any information in social media or websites, especially information that can contravene Malaysia's laws," the commission said, The Strait Times reported. 

The Army has also warned that it will be forced to intervene if the protests get out of hand. 

Given that Bersih has not received the official permits from the Kuala Lampur authorities to carry out the two-day protest, violence is likely to break out, local media reported. 

The anti-Razak protesters have widely been using social media and phone networks to mobilise crowds for the protest. 

Anger against the Malaysian PM has grown since reports last month claimed that up to US$700 million had landed in Razak's accounts before the 2013 elections. 

Razak had reportedly said the money were "political donations" from the Middle East.
