DMK leader M K Stalin Wednesday said a Congress-DMK alliance at the Centre had always proved successful 'whenever the country faced a threat'.
"Whenever the country faced a threat, the Congress and the DMK alliance has been formed and was also successful", he said, but did not elaborate.
He was reacting to Prime Minister Narendra Modi's opportunism barb at a NDA rally at Kancheepuram earlier in the day near chennai.
Modi had said that if there was one party that has abused Article 356 again and again, it was the Congress.
Even the DMK had become a victim, he said and hit out at the Dravidian party for joining forces with Congress, saying "opportunism has prevailed over values."
He also felt that the BJP alliance in Tamil Nadu was opportunistic and was formed due to 'coercion'
