According to ECP sources, the verification of voters' lists was scheduled to be completed by February 11, but will now be completed by February 16.

The additional time was requested due to difficulties being faced owing to the law and order situation prevailing in Karachi.

The approval for a five day extension will be given by the Election Commission of Pakistan.

In December 2012, the Supreme Court had directed the ECP to conduct verification of voters' lists in Karachi with the assistance of the army and Frontier Corps.
