Political use of anticorruption agencies?

Benazir Bhutto accuses Musharraf of using the country’s anticorruption agency for political purposes;

Of course Musharraf's regime, to legitimize its coup and divert attention from the institutionalized corruption of the military, accuses Pakistan's secular, democratic parties of corruption. But according to Transparency International, 67 percent of the people believe the regime is corrupt, surpassing the rate for past civilian governments. Musharraf's regime has lasted twice as long as any civilian government in Pakistan. Yet not one of its ministers or key political supporters has been investigated.

The National Accountability Bureau has persecuted opposition leaders for a decade on unproven corruption and mismanagement charges, hoping to grind them into submission. However, when politicians accused of corruption cross over to the regime, the charges miraculously disappear. Musharraf's regime exploits the judicial system as yet another instrument of coercion and intimidation to consolidate its illegitimate power. But the politics of personal destruction will not prevent me and other party leaders from bringing our case before the people of our nation this year, even if that could lead to imprisonment.
