The movement for electoral reform, Bersih, which has been at the forefront of mammoth free and fair voting rallies in the country, has thrown its weight behind the May Day protest and urged Malaysians to turn up in force.

The May Day protest, in conjunction with International Worker's Day on May 1, is aimed at voicing out against the goods and services tax (GST), which was passed in Parliament this month and will come into effect on April 1 next year.
