Congress leader Manickam Tagore has reacted sharply to reports that allies of Tamil Nadu's ruling DMK - with whom the Congress will contest next year's Assembly election - has called for action against the national party's data unit chief, Praveen Chakravarthy.
Tagore said comments urging senior Congress leader Rahul Gandhi, who is also the Leader of the Opposition in the Lok Sabha, to act against Chakravarthy raised a "fundamental question".
