An umbrella group of non-governmental organisations called the Muslim Defenders Movement plans to hold a demonstration on Saturday to protest against what it deems to be efforts by the new government to undermine the interests of the country's Malay Muslim majority.

"Let us come together with others from our religion to express our unhappiness towards several developments which threaten Islam and Malay rights, sons of the soil of our beloved nation," said the conservative NGO on its Facebook page.
