MDMK chief Vaiko on Sunday said AIADMK supremo Jayalalithaa was a 'fit candidate" for the prime minister's post and he would raise his voice in her support when the occasion arose.

"She is a dynamic leader with versatile capabilities... She is a fit candidate for the PM's post. When the occasion arises, I will raise my voice in her support," Vaiko, whose party is an ally of the AIADMK for the Lok Sabha polls, told reporters.

When pointed out that Jayalalithaa herself had declared that she had no aspirations to become prime minister, he said, "She may not have any aspirations. But we will raise our voice."
