Former Madhya Pradesh Chief Minister Kamal Nath has approached the Supreme Court challenging the Election Commission's decision to remove him as a "star campaigner" ahead of the by-elections in the state next week. The powerful election body had said the 73-year-old leader's star campaigner status was being revoked for "repeated violation of model code of conduct" and for "complete disregard" of warnings to him. Kamal Nath, being a leader of a political party, had repeatedly "breached ethical and dignified behaviour", the commission said in its order.
