ISLAMABAD: Chairman National Accountability Bureau (NAB) Admiral (retd) Fasih Bokhari on Saturday claimed institutions were being used as political ammunition, DawnNews reported.

Speaking to media representatives in Karachi, Bokhari said employing powers of institutions against political opponents was perilous.

The bureau's chairman moreover emphasised that planning was important in order to restrict corruption, adding that there was a need to tackle corruption at the lower levels.

Bokhari further said it was also important to bring those to account who had been involved in corruption in the past.

The statements come in the wake of a show-cause notice for contempt of court issued by the Supreme Court to Bokhari over a letter sent by him to President Asif Ali Zardari.

The letter had directly accused members of the superior judiciary of trying to influence the outcome of the coming general election.

In the letter dated Jan 27, Bokhari had cast serious doubts over the role of the Supreme Court which he said “could be seen as pre-poll rigging”.
