MDMK chief Vaiko on Saturday exuded confidence that DMDK will opt to join the four party People’s Welfare Front over DMK to fight the May 16 Assembly elections in Tamil Nadu.

"DMDK leader Vijayakanth supported AIADMK in the previous elections, opposing corruption in DMK. I don’t think he will join DMK now to prevent AIADMK from coming to power," he said.

He said PWF had completed their campaign in 22 districts and would strictly comply with the model code of conduct.

To a query on DMK backing Tamil Nadu government’s decision to release the seven convicts in the Rajiv Gandhi assassination case, he said DMK could have taken the step earlier but had not done so.

Asked about poll surveys, he said the PWF does not believe in the strength of surveys but in the support extended by the people to the front.

He alleged that there were moves to distribute money to voters by AIADMK and DMK in the run up to the polls and urged the Election Commission to take steps and prevent it.

"There is a silent and invisible revolution taking place and PWF will win the elections," he said.
