TMC leader Derek O'Brien said, "Electoral reforms is a very important issue for us as we are battling the world's most corrupt party... This was the most unfair election in the history of Indian democracy. It was unfair, unconstitutional and and unjust. It was run by an unfair and unjust EC."

"Now, the Parliament must step in and decide if they want to amend the law, bring in a legistlation, they have to do something otherwise they will sell the country. BJP itself is corrupt, buys elections, buys MPs...," he alleged. He questioned the BJP about "how it got rich by 81 per cent after demonetisation" and alleged that it was the "most capitalist party in the world."

O'Brien said, "95% of the total electoral bonds funding went to BJP. The party has a hosepipe election strategy. What is in the hosepipe? Free flow of money. Challenge the BJP to negate these facts."

The BJP, he claimed, got Rs 342 crores from "unknown sources". "We are proud of our rags. We got only Rs 10 lakh from "unknown sources"," the TMC leader said. All the figures he quoted were from returns filed by political parties and those put up by Association For Democratic Reforms.
