The government has told bureaucrats and other officers that tweets and posts on their official social media accounts should be made first in Hindi. An English version is optional.
The Home Ministry's instruction - dated May 27 - calls for full compliance in Hindi-speaking states.
With more than half of India's 1.2 billion people using another language as their mother tongue, the push for Hindi may be controversial, especially in the southern and eastern states, where local languages or English are preferred.
The directive has been aggressively opposed by M Karunanidhi, the chief of the DMK, who says the Prime Minister seems to have pushed the promotion of Hindi to the top of his agenda.
"The PM should focus on development rather than on promoting Hindi", the 89-year-old said in Chennai today. (

He said the Home Ministry's decree amounts to "an attempt to treat non-Hindi speakers as second class citizens." Mr Karunanidhi's party failed to win a single one of Tamil Nadu's 39 parliamentary seats in the national election that swept the BJP to power. (

Home Minister Rajnath Singh clarified in a tweet, "The Home Ministry is of the view that all Indian languages are important. The Ministry is committed to promote all languages of the country."
Junior Home Minister Kiren Rijiju, who is from Arunachal Pradesh, said, "We have to promote Hindi because it is our official language. That does not mean we are going to discourage the use of regional languages."
He said a meeting today with his department was conducted in Hindi.
"Language battlefields have not yet dried. History has recorded anti-Hindi agitation," Mr Karunanidhi said, whose party won its first state election in Tamil Nadu because of the lead role it played in a violent resistance in 1965 to a move to make Hindi the official language across the country.
Riots tore through Tamil Nadu and calm was restored after Prime Minister Lal Bahadur Shastri reiterated a commitment made by Jawaharlal Nehru that English would be used to communicate between the union government and non-Hindi-speaking states.
