Mugilan said the movement, to be launched on May 30, will explain why Samy should resign as president.
"We will explain to the people and conduct a signature campaign," The Star quoted Mugilan, as saying.
"I have no personal agenda against Samy Vellu. My agenda is the poor Indians and MIC members who have been cheated," he added.
He also said that the movement would exist as long as Samy held on to his office.
Earlier, the call for Vellu's resignation had further gained momentum with two high-ranking MIC leaders joining Mugilan in making a similar demand.
MIC Central Working Committee (CWC) member K.P. Samy said Vellu had overstayed his tenure as party President and must leave for the MIC to recover from its current predicament.
"We lost heavily in the last general election and have also lost the support of the community that we profess to represent. The MIC is in bad shape and to rejuvenate it, Samy Vellu has to leave," K.P. Samy said.
Another CWC member G. Kumar Aamaan called for Vellu's early resignation, saying that Mugilan's sacking was a way for Vellu to silence his critics.
