"The grand old party Congress' grand new leader has tried to give communal colour to the elections by his statement in which he co-related the Congress' 'hand' with various religious figures. This is a clear cut case of corrupt practice. There should be action against both Congress and its leader," Naqvi told reporters after filing the complaint with Election Commission.
At Congress' 'Jan Vedna Sammelan' earlier this month, Gandhi had made comments co-relating his party's poll symbol 'hand' with gods, violating the provisions of the Representation of the People Act, 1951, model code of conduct and the guidelines issued by the Supreme Court, BJP has alleged in its complaint.
