New Delhi, Nov 24 (PTI): BJP MP Ram Jethmalani today criticised his party's attack on the government over the appointment of the CBI Director alleging that the move was "instigated" by the "most undesirable rival".

Jethmalani also had a word of praise for the government action in the appointment of Ranjit Sinha as CBI Director and contended that the decision "for a change, has averted national calamity".

"...I was astonished to read that the BJP has attacked the Prime Minister and the Congress party for what the party calls the fast tracked appointment of Mr. Ranjit Sinha as the Director of the CBI," the veteran Parliamentarian said in a letter addressed to BJP President Nitin Gadkari, copies of which were marked to the Prime Minister and the media.

"I regret that this criticism is a result of complete ignorance of relevant facts and has been instigated by a most undesirable rival who had to withdraw his petition before the CAT yesterday as a result of the appointment," Jethmalani said.

Arun Jaitley and Sushma Swaraj, Leaders of the Opposition in the Rajya Sabha and the Lok Sabha respectively had written letters to the Prime Minister, saying that appointment of the new CBI Director should not have been done when the Rajya Sabha Select Committee had recommended that such appointments should be done through a collegium.

The Prime Minister had rejected BJP's demand to hold in abeyance appointment of Sinha as CBI Director and termed as "unwarranted" insinuation the charge that the decision was to preempt the procedure recommended by the Select Committee on Lokpal.

"The rival has powerful friends everywhere who do not know what a disaster it would have been if he could manage to become Director of CBI in place of Mr. Sinha," Jethmalani said.

Jethmalani said he would send to Gadkari documents to show how the government action "for a change, has averted a national calamity." "I have to request you to ensure that these critics from our Party refrain from further comments till they know all the facts. I claim to know the facts from my own knowledge," he said.

Delhi Police Commissioner Neeraj Kumar had approached the Central Administrative Tribunal (CAT) against the government's decision to not consider his name for the post of CBI Director but withdrew his application after the appointment of Sinha.

Kumar had moved the tribunal aggrieved over non-inclusion of his name among the three officers shortlisted by the Central Vigilance Commission (CVC) for being considered for the post of the next CBI Director.
