NAB meaning in Governmental ?

The National Accountability Bureau (Urdu: قومی احتساب بیورو‎; abbreviated NAB) is an autonomous and constitutionally established federal institution responsible to build efforts against corruption and prepare critical national economic intelligence assessments against economic terrorism for the Government of Pakistan. It is headed by Justice (R) Javed Iqbal as its chairman.

The NAB is empowered to undertake any necessary prevention and awareness, in all means, in addition to enforce its operations against economic terrorism and financial crimes. Since it was established by Pervez Musharraf on 16 November 1999, its sphere of operations has been expanded and extended. The constitution grants power to launch investigations, conduct inquiries, and issues arrest warrants against individuals suspected of financial mismanagement, economic terrorism, corruption (all in private-sector, state-sector, defence-sector, and corporate-sector), and directs cases to the accountability courts.

Established by Ordinance No. XIX, its powers have been extended to conduct inquiries at higher levels by Article 270AA of the Constitution of Pakistan. With its chief headquarters located in Islamabad, it has four regional offices in the four provinces, as well as the four capital territories of Pakistan.
