Congress president Rahul Gandhi, on Tuesday, demanded the resignation of Railways and Coal Minister Piyush Goyal over the allegations of his involvement in a Rs 48 crore scam. In response, Goyal retorted by saying that he was a "kaamdaar" and not a "naamdaar", unlike Gandhi.

Goyal's comment drew reference from Prime Minister Narendra Modi's "naamdar versus kaamdar (dynast versus worker)" jeer for Rahul Gandhi while he was campaigning for the Karnataka Assembly polls.

Rahul Gandhi took to Twitter to attack the Railway Minister. "Piyush Goyal's, 48 Crore FlashNet Scam is about deceit, conflict of interest and greed. The evidence is on the table. Yet, the media will not touch the story. It is a tragedy for our country when journalists entrusted to stand for the truth, will not speak, Gandhi said on Twitter, using the hashtag #GoyalMustResign," read his tweet along with a photo alleging that Goyal sold his stock of Flashnet Info Solutions to Piramal group, which has interests in the power sector, at 1,000 times the face value.

Goyal countered with a tweet, which read, "Till 26th May 2014, before I became a Minister, I was a professional Chartered Accountant and investment banker. Unlike you, Mr Rahul Gandhi, I have not learnt well the art of living without working. I am also a 'kaamdaar' (worker) and not a 'naamdaar' (dynast)."

Over the past few days, the Congress has stepped up attack against Goyal. "Piyush Goyal makes dubious business deals benefiting companies linked to him through his position. However, PM Modi doesn't utter a single word on this," Gandhi had said on Sunday.

Demanding the sacking of Goyal, the Congress cited an alleged conflict of interest between the Minister and the Piramal Group. Goyal, as per Registrar of Companies (ROC) documents, sold a company jointly owned by him and his wife to the Piramal Group at a profit in 2014, while he was the minister of state for power. However, the Piramal Group had said that there was nothing malafide in the deal and it was an independent chartered accountant who had assessed Flashnet Info Solutions Private Limited at Rs 47.96 crore.
