The MDMK is part of the seven party alliance headed by the Dravida Munnetra Kazhagam.
MDMK chief Vaiko, in a statement, said that his party was committed to the alliance's victory in the polls.
The MDMK's basic principles were "political honesty and civilised polity" and these were like "two eyes" to the party, Vaiko said in an apparent reference to the DMK treasurer Arcot N Veerasamy's statement that he was of not "following honest politics."
Vaiko said MDMK had paid a heavy price for following probity in public life and honesty in politics.
"We never thought of short term temporary political gains and even in 2001, when MDMK was compelled to leave the DMK front, we did not join the other front in order to get few assembly seats," he said.
Denying that MDMK had worked against the DPA at any time, he said that the party stuck to the DPA in the last Lok Sabha polls despite the fact that it could not get the seats it wished to contest.
"We dedicated ourselves fully for the victory of the DPA candidates in all the 40 Lok Sabha seats," he said.
On the delay in giving the 'wish list' to the DMK as decided at the meeting of the DPA leaders on February 8, Vaiko said he was consulting with his party leaders and district secretaries to prepare the list and thought of taking two more days.
"When the process was going on, I was mentally hurt by the remarks that whether MDMK continued in the DPA, that too when I had thanked DMK President M Karunanidhi for accepting my plea to upgrade a high school in my village as a higher secondary. I am not ungrateful," Vaiko said.
Vaiko said he had already announced at New Delhi on February 14 that MDMK continued in the DPA and there was no change in the stand.
Vaiko said he had already expressed regrets for MDMK propaganda Secretary Nanjil K Sampath's remarks against the DMK. "These remarks violated the coalition dharma and mounted to violation of party discipline," he said.
