BENGALURU: Karnataka Rakshana Vedike activists on Friday launched a state-wide protest against the Centre’s alleged imposition of Hindi on Non-Hindi speaking states , as part of which they blackened Hindi signages on national highways The KRV’s Black Day coincided with the Centre celebrating the day as Hindi Diwas to mark Hindi written in Devanagari script becoming an official language of Union government under the Article 343 on September 14, 1949.“The present regime at the Centre is propagating its hidden agenda of imposing Hindi on the country where a majority of population is non-Hindi speaking. Today’s protest is to resist the parochial policy of the Centre,” said KRV president T A Narayana Gowda , who led a sit-in held at the Mahatma Gandhi statue in Gandhi Nagar.The KRV activists blackened the milestones written in Hindi on NH 48 near Davanagere, and signages on other highway stretches at Yadgir, Mysuru, Kolar, Chikkaballapur and Shivamogga.Even as the pro-Kannada organisation is continuing its efforts to mobilise non-Hindi speaking states against the BJP-ruled Centre’s move to impose Hindi in them, Narayana Gowda said the KRV is planning a conference of the southern states on the language policy shortly.
