"I hope that today's sentence and judgement will act as a deterrent for politicians in getting involved in corruption in future," Naidu, a BJP MP and former party president, told a press conference here.
"The CBI court's sentence for Lalu Prasad and Jagannath Mishra is expected. Though justice is delayed, but it is not denied," he said.
He said that Congress MP Rashid Masood was also awarded a four-year jail term recently.
"The fodder scam case took 16 years, Masood's case 17 years and other politically important cases like 2G, coalgate, and Commonwealth Games, among others, are facing abnormal delays," the BJP leader said.
There are delays on the part of the prosecuting agencies as has happened in the case of Lalu Prasad, he said.
"In the coming session of Parliament, BJP will insist on setting up of fast-track courts to deal with cases where politicians are involved in corruption or criminal interference," he said.
