Youth group Solidariti Anak Muda Malaysia (SAMM) had given the ultimatum to the ruling coalition under the leadership of Prime Minister Datuk Seri Najib Razak to postpone the implementation of the Goods and Services Tax (GST).
SAMM national coordinator Mohd Faizal Ab Rahim said a failure to do so would result in the government facing a huge protest to be held on May 1.
"The public are getting impatient, the ruling coalition appeared to have lost the respect of the people,"he said in a statement Apr 8.
Mohd Faizal said the BN parliamentary had not acted for the benefit of the public but that of themselves by supporting GST.
"This is leaving the public with not choice, but to go down to the street to show their protest," he said.
Mohd Faizal said the group initiative to cooperate in monitoring the plan for GST had also previously been thwarted.
He said however after a few initiative of their own they had taken the stance not to completely oppose the GST but that the taxes could only be implemented after a few things had been rectified.
This include reducing wastages and leakages as well as ensuring that the income level of the public is at an acceptable level.
