MDMK, which preferred to boycott the assembly polls after failing to clinch a seat sharing deal with AIADMK, on Friday hailed the defeat of DMK, saying democracy "has triumphed over money power".
In the last five years, Tamil Nadu under the DMK's 'dynastic rule' was experiencing frequent power cuts, rise in essential commodity prices, failure of law and order among many others, MDMK chief Vaiko said in a statement.
"People of Tamil Nadu have trounced money power and crowned deomcracy," he said.
People's power had turned into a "giant wave" and swept away DMK government, Vaiko said.
"Though my party has not been able to participate in the polls, it has been conducting a series of campaigns against the DMK," he said.
The voters had sent out a lesson that in future none can win elections by "misusing their authority", he added.
