Lahore:  Pakistan's main opposition PML-N chief Nawaz Sharif on Saturday said his party will back whatever decision the Supreme Court makes in a contempt case against Prime Minister Yousuf Raza Gilani for failing to revive graft cases against President Asif Ali Zardari.

The former premier said the PML-N would back the Supreme Court if it makes a "big decision" against Gilani's government.

Sharif was referring to the possible conviction of Gilani in the contempt of court case that was initiated after the premier failed to approach Swiss authorities to reopen cases of alleged money laundering against Zardari.

"In future, if the court makes some big decision, we will make sure it is implemented," Sharif said while talking to reporters here.

He said the government had continuously defied the Apex Court's orders.

Gilani has said he cannot act on the Apex Court's orders as long as Zardari is in office as the Constitution provides immunity to the President in Pakistan and abroad.

Sharif parried a question about allegations that he had received money from the ISI when the spy agency distributed millions of rupees among politicians to rig the general election in 1990.

Banker Yunus Habib, who provided the money that was distributed among the politicians, has alleged that Sharif and his brother, Punjab Chief Minister Shahbaz Sharif, were among those received pay-offs.

The Apex Court is hearing a petition against the funding of the politicians by the ISI.

In a related development, Punjab Governor Latif Khosa, a senior leader of the Pakistan People’s Party said that Gilani would continue as the Prime Minister even if he was convicted for contempt by the Apex Court.

"The PPP has decided that Gilani will not be replaced if he is convicted in the contempt case.

"He will not be disqualified from holding office even if the decision goes against him," said Khosa, who is also a leading lawyer.

Khosa noted that the Supreme Court had not yet issued notices to the Sharif brothers for allegedly receiving Rs 3.5 million and Rs 2.5 million, respectively, from the ISI in 1990.

"It shows the court's leniency towards them. In the case of the PPP, the courts go the extra mile to do justice," he said.

Khosa pointed out that the courts had stopped the National Accountability Bureau, an anti-corruption watchdog, from investigating corruption cases against the Sharifs in Pakistan and abroad and said this was "very unfortunate".

The Governor said the Sharifs and other characters who were once backed by the ISI should be tried for committing treason under Article 6 of the Constitution.
