Bharatiya Janata Party leader and Rajya Sabha MP Subramanian Swamy on Tuesday created ripples on social media when he tweeted, "In my opinion, this lieutenant governor of Delhi Mr Jung is unsuited for this high post. He is another 420 like Kejri. We need a Sangh person in Delhi.” The number 420 in the Indian context refers to a fraudster.

Delhi Lieutenant Governor Najeeb Jung and Chief Minister Arvind Kejriwal have been involved in a dispute over who runs the administration of the nation's capital. The Delhi High Court, on August 5, had ruled that the national capital was a Union territory "under the administrative control of the lieutenant governor" and that it "does not acquire the status of a state”.

Swamy was recently embroiled in a controversy over his critical comments on Reserve Bank of India Governor Raghuram Rajan. He had claimed Rajan was "mentally not fully Indian" andwrote to Prime Minister Narendra Modi asking him to dismiss Rajan, whose term as governor ends in next month. Rajan had announced later that he would not take a second term as RBI's chief.

The prime minister, however, had dismissed Swamy's request and praised the RBI governor's work. Modi said, “Those who are creating controversies are being unjust to Raghuram Rajan… I believe Rajan’s patriotism is no less than any of ours… I appreciate the work he has done… Whatever post he (Rajan) holds, wherever he is, he is someone who will continue to serve the country,” the Prime Minister said.

Swamy had also said he will "expose 27 other bureaucrats". Finance Minister Arun Jaitley and Chief Economic Advisor Arvind Subramanian were also at the receiving end of the Rajya Sabha member's criticism.
