Union minister and BJP leader Pon Radhakrishnan on Tuesday alleged that the Election Commission was "silent" on complaints against the ruling AIADMK.
"The functioning of the EC has created the doubt, if it was biased to the ruling party," he told reporters at the airport in Madurai, but did not elaborate.
On the fishermen and Sri Lankan Tamils' issue, he said political parties talk about these issues only during the elections.
On the other hand Prime Minister Narendra Modi "is taking several steps for the benefit of the Sri lankan Tamils and fishermen," he said, adding, the PM would come to Tamil Nadu for campaigning.
He claimed that MDMK chief Vaiko had formed the People's Welfare Front only to "help" DMK or AIADMK to come to power.
