Jaitley has come under severe attack for his handling of the economy.
The latest salvo was fired by former NDA finance minister Yashwant Sinha.
Sinha's salvo came in the form of an opinion article in Wednesday's Indian Express newspaper.
Sinha, in his piece, blamed Jaitley squarely for botching up the economy.
Sinha started his piece by saying: "I shall be failing in my national duty if I did not speak up even now against the mess the finance minister has made of the economy. I am also convinced that what I am going to say reflects the sentiments of a large number of people in the BJP and elsewhere who are not speaking up out of fear."
He then went to ask: "So, what is the picture of the Indian economy today?," Sinha asked in his piece.
And to answer: "Private investment has shrunk as never before in two decades, industrial production has all but collapsed, agriculture is in distress, construction industry, a big employer of the work force, is in the doldrums, the rest of the service sector is also in the slow lane, exports have dwindled, sector after sector of the economy is in distress, demonetisation has proved to be an unmitigated economic disaster, a badly conceived and poorly implemented GST has played havoc with businesses and sunk many of them and countless millions have lost their jobs with hardly any new opportunities coming the way of the new entrants to the labour market. For quarter after quarter, the growth rate of the economy has been declining until it reached the low of 5.7 per cent in the first quarter of the current fiscal, the lowest in three years."
The other person who has relentlessly attacked Jaitley recently is BJP Rajya Sabha MP Subramanian Swamy.
Former RBI governor Raghuram Rajan's exit had also been preceded by a relentless attack by Swamy.
