Prasad, the former Railway Minister who was not preferred by the Congress leadership in the new government, also accused her of neglecting Bihar in the budget.
In a combative mood, Prasad said he was not bothered by the Minister's declaration of coming out with a white paper on the organisational, operational and financial situation and performance of Railways in the past five years when Prasad was at the helm.
"This is not an embarrassment (that a white paper is coming out). Let her bring out white paper. I am not bothered," he told reporters after Banerjee presented the rail budget in Lok Sabha.
"Is this a budget? She has just read out what I had announced during my stint...She suffers from a complex," he said.
Prasad claimed there was "nothing new" in the budget and that she had just read out what he had prepared during his stint. "She has used my achievements as a base to build her vision," he said.
