Chennai: DMK president M. Karunanidhi on Wednesday gave a new twist to the political situation in Tamil Nadu, saying his party would support its “ungrateful” former ally Congress if the party repented for their acts. Starting his election campaign here, Karunanidhi said the Congress was down in many states as it was an ungrateful party. He said the Congress put the DMK and its friends in difficulty and it was now suffering because of that. [caption id=“attachment_1452821” align=“alignleft” width=“380”] Karunanidhi.

He said his party would forget the betrayal and support the Congress to save them from trouble. According to him, it will be a sort of general amnesty for the Congress. Karunanidhi said the DMK will not forgive ungrateful people even if they are brothers or sons. “As far as I am concerned, principles are important than children,” Karunanidhi added. The DMK had earlier refused to align with the Congress, forcing the latter to go it alone in the general election. IANS
