Islamabad: The opposition Pakistan Tehreek-e-Insaf (PTI) on Friday accused the government of backtracking from its commitment to constitute a judicial inquiry commission on 2013 general elections and warned it may resume street agitation.

PTI chairman Imran Khan told reporters the government had informed his party on Thursday of its intention to make changes to the mutually agreed terms of reference of the proposed commission.

But Finance Minister Ishaq Dar told a private television channel that the government was not seeking any alteration in the memorandum of understanding with PTI.

Dar, who had led negotiations with PTI, asked Imran Khan “not to believe in mere gossip”.

Negotiators from both sides had met and settled the terms last week and jointly announced satisfactory outcome to end the long-drawn out tussle between them over the issue.

“After having concluded an understanding the government now wants the agreed terms because of fears that the probe will expose the fraud committed in 2013 polls,” Khan said.

“This is absolutely unacceptable,” the PTI leader said, adding that his party would be left with no option but to use its “street power”.

“When we restart agitation the government will no longer be able to function,” he said.

Khan had led a record 126-day sit-in by party workers and supporters last year near the parliament in Islamabad as the two sides wrangled over the judicial commission issue.

The PTI leader had called off the sit-in after an attack by militants on December 16 in which around 150 people, mostly children, were killed at an army public school in Peshawar, capital of northwestern Khyber Pakhtunkhwa province governed by his party.
