The BJP in Tamil Nadu has accused Congress MP Rahul Gandhi of violating the Model Code of Conduct ahead of next month's Assembly election - by holding a "surrogate election" during an interaction with school students from Kanyakumari district earlier this week. The chief of the party's state unit, L Murugan, wrote to the Chief Electoral Officer, alleging "the political campaign in educational institutions has violated provisions of (the) Model Code of Conduct" and calling for "strict action, including prohibitory orders" against Mr Gandhi.
