President PML-N Mian Nawaz Sharif Wednesday described October 12, 1999 as a black day when the then army chief Gen. Pervez Musharraf staged a military coup - the fourth time in the country's history that a military dictator usurped power.

Addressing the PML (N) sit-in outside the Parliament, he said that during the Musharraf's era, judges were arrested and the Constitution was distorted to serve the objectives of the dictator.

He said his government was removed when the country was on what he claimed, the path of progress and development. He called for implementing the Supreme Court's decision on Karachi's law and order situation to restore durable peace.

He was of the view that resolution adopted by the APC was needed to be presented for discussion in the Parliament.

He said government should take steps to overcome problems like power and gas loadshedding. Some other leaders of the PML(N) also spoke on the occasion.
