Rajas request to Lok Sabha Speaker Meira Kumar comes days after Attorney General GE Vahanvati blamed him for various issues before the joint parliamentary committee (JPC).
He has also been blamed for the 2G scam by other witnesses before the special CBI court.
The truth of the matter is being suppressed on the basis of preconceived notions, deliberate bias, faulty investigation and erroneous conclusions. ...perhaps the most telling example of this situation is the judgment of the Honble Supreme Court dated 02.02.2012, where specific and prejudicial observations were made against me without giving me a hearing, Raja wrote in the letter.
There was no immediate reaction of JPC chairman PC Chacko to the request.
Congress spokesperson Rashid Alvi steered clear of the issue, while an AIADMK leader said it was a fight between the DMK and Congress and his party would not get into it.
Raja met Kumar at her office on Friday and handed over a letter expressing his willingness to appear as a witness before the JPC.
