Pakistani Prime Minister Yusuf Raza on Sunday played down fears of growing tension between the government and judiciary.
Speculation has swirled for weeks that Pakistan's Supreme Court would uphold the scrapping of an amnesty law, possibly opening the door to attempts to prosecute government leaders including President Asif Ali Zardari.
The amnesty law allowed some current politicians including Zardari to return after years of exile. It was thrown out in December 2009 by the Supreme Court, which must now pronounce on a government attempt to overturn that ruling.
"Nobody should expect that there will be any confrontation between (state) institutions as long as we (the government) are here," Gilani said in a televised address to the nation.
There are several cases outstanding against Zardari in Switzerland involving accusations of money-laundering, which were withdrawn in 2008 after he was elected president.
Government ministers, officials and Gilani often say the government cannot reopen cases against Zardari because the constitution gives him presidential immunity.
With the government facing a huge task in rebuilding after summer floods that made over 10 million people homeless, and in fighting Taliban insurgents who remain effective despite military offensives, analysts say the Supreme Court is unlikely to try to remove him now.
The opposition has also not indicated any intention to agitate for his downfall, although fears of fresh political upheaval persist.
Powerful army chief General Ashfaq Kayani is apparently trying to ease tension between the government and the judiciary, and Gilani appeared to acknowledge this.
"If we can work with the military, if we can develop consensus with political powers, then we can definitely move forward with judiciary," said Gilani.
"Whatever the situation is, we should think of how the judiciary and government can provide justice to the people."
In London, opposition leader Nawaz Sharif was highly critical of Zardari, who has denied any wrongdoing.
"There are corruption cases inside and outside the country against him and he cannot get rid of them. The best way for him is to apologise to the nation and return the nation's money and respect institutions," Sharif told a news conference.
