Islamabad, Sep 15 - Chaudhry Nisar Ahmed, leader of opposition in Pakistan's National Assembly, Tuesday slammed President Asif Ali Zardari for his comment that the former president and military dictator Pervez Musharraf had resigned as 'part of a deal'.

If Pervez Musharraf's exit was part of an international deal, Zardari too became president with the help of international powers and thus should be answerable to the nation, Chaudhry Nisar Ahmed was quoted as saying by Geo News.

'Zardari's statement is against the national sovereignty and independence and it violated the grace of parliament,' Ahmed said.

Zardari during an Iftar party earlier told reporters that the former president had resigned as part of a negotiated settlement that was guaranteed by 'international and local powers'.

'All international and local powers, which have stakes in the region, were guarantors of Pervez Musharraf's negotiated resignation,' Daily Times Tuesday quoted Zardari as saying.

He said Musharraf could not be tried under Article 6 of the Constitution as was being demanded by some opposition parties, especially the Pakistan Muslim League-Nawaz (PML-N).
