According to Pakistani media reports, the NAB is not likely to either arrest the Prime Minister or send a reference against him while he is in his office. The NAB has been ordered to arrest Raja by the Supreme Court of the country in the Rental Power Projects (RPPs) case.
NAB Chairman Fasih Bokhari is of the opinion that it was his prerogative to get approved a reference against the accused or close the case and it was in the Supreme Court's domain. However, to keep the process alive, the NAB may effect few arrests but not likely to touch the Prime Minister and plunge the Pakistan into Constitutional chaos.
Pakistan is already under siege internally by the million man march of the cleric Tahir-ul-Qadri, demanding the resignation of the federal government and an interim government, backed by the army, take over. The country also has to respond to the charges of provocation on the border by the Indian government and a vacuum at the government level could have been chaos.
The power vacuum is a sure opportunity for the army to step in and impose martial law. And, the army rule is not good for India. Under martial law, the Inter-Services Intelligence (ISI) will get a free hand to expand its funds base, influence in Kashmir and support terrorist groups, brazenly.
Meanwhile, the Pakistani political establishment is rejoicing over the court verdict not because it puts the Prime Minister in the firing line but because it took away the attention from Tahir-ul-Qadri's challenge and demands. Qadri had announced to the public about the Supreme Court judgement and seemed to believe that it was half-way to his agenda but by evening it had proved counter-productive with Pakistan shifting its attention the Prime Minister's survival.
