NEW DELHI: Staying true to his promise of training guns on bureaucrats 'loyal' to the Congress, Bharatiya Janata Party (BJP) leader Subramanian Swamy on Wednesday said that he wants Chief Economic Advisor Arvind Subramanian to be sacked, as he had badmouthed India in the international arena and had also encouraged the grand old party to become rigid on their GST Bill clauses.

After he tweeted against Arvind, Swamy reiterated his salvo he had used against RBI Chief Raghuram Rajan, saying that the CEA was a 'green card holder' and was probably not an Indian citizen.

"He used to work in America and he is also a green card holder type. I don't even know if he is a citizen or not but I'm sure he has a green card. There was this American Congress Committee for pharmaceutical purposes and they held a hearing to figure out India's opinion on the matter. There he said in a statement that India was not working according to America in this matter and for that, they should be taught a lesson in WTO. How can we can such a person an advisor here?," Swamy said.

Continuing his assault, he added that when Arvind was appointed by the Indian government, he gave a note to the Finance Ministry asserting that the clauses given by the Congress in the GST Bill were absolutely justified.

"I think that such people who can fail our government should be tossed out. Now, it's been two years and I think it's about time," he added.

The senior BJP leader also said that he had a list of 27 people with him and that he will 'fix' them soon.

Earlier in the day, Swamy had launched a scathing attack on Arvind in a series of tweets.

"Who said to US Cong on 13/3/13 the US should act against India to defend US Pharmaceuticals interests? Arvind Subramanian MoF !! Sack him!!! Guess who encouraged Congi to become rigid on GST clauses ? Jaitely's economic adviser Arvind Subramanian of Washington DC," he tweeted.

This development comes days after Swamy announced that his next 'project' is to expose a group of bureaucrats loyal to Congress Chief Sonia Gandhi.

"My next project is to expose 27 bureaucrats who are in various Ministries and loyal to TDK. They were handpicked and positioned by PC," Swamy said in a tweet.

Earlier, Swamy had welcome Rajan's decision to leave his post as the Reserve Bank of India (RBI) Governor on the completion of his term, saying that he had taken such a step in order to save his 'self respect'.

"Was he getting a second term in the first place? How do we know that he was getting a second term? I have no information that he was getting a second term. So if he says he wants to go and wants to save his self respect, I have no problem. Let them pretend that he is giving up and going but as long as he goes, it's good," Swamy said.

Swamy had written to Prime Minister Narendra Modi in May asking for the dismissal of the Reserve Bank of India governor.

Rajan had earlier announced that he would return to the academic world at the end of his term on September 4, 2016, adding he will always be available to serve his country when needed and asserted that his 'successor' would take the nation to new heights.

Rajan is currently on leave from the Chicago Booth School of Business where he holds the post of Distinguished Service Professor of Finance.
