London ( CNN ) -- With his fate at home hanging in the balance , Pakistani Prime Minister Yousuf Raza Gilani repudiated U.S. claims that Pakistan was falling short on fighting the war on terrorism and said instead that his nation was operating on a trust deficit with Washington . `` There 's a trust deficit between both the countries , between both the governments , '' Gilani said in an interview with CNN in London . `` That is the reason we are wanting to work for new terms of engagement and cooperation with the United States . '' Pakistan has been a key U.S. ally , but relations between the two nations have been strained in recent months , especially after last year 's killing of Osama bin Laden on Pakistani soil and a NATO airstrike in November that killed 24 Pakistani soldiers . Amid a lack of harmony , the Obama administration has said it is not convinced Pakistan is pulling its weight . At the end of an Asia tour Tuesday , U.S. Secretary of State Hillary Clinton said Pakistan ought to do more in fighting extremism . Gilani countered that his country was doing all it could in partnership with the United States . `` If there is any credible , actionable information , please share with us , because are already working with you , '' he said . `` My ISI is working with the CIA . What else do you want ? '' The ISI , or Inter-Services Intelligence , is Pakistan 's powerful spy agency , which some U.S. officials have charged is protecting militant groups . How can relations between the two nations , strained in recent months , improve ? `` One point , '' Gilani said . `` That is mutual respect and mutual interest . '' A lack of trust is not the only stain marring a critical relationship . Pakistan has said it wants an end to U.S. drone strikes on its territory , and Gilani made the point again Tuesday . `` We always take drones as counterproductive , and it 's not lawful , '' Gilani said . Back at home , Gilani faces myriad national woes : a faltering economy , widespread poverty and corruption . And now , his own future . He was convicted last month of contempt for his refusal to revive old corruption charges against President Asif Ali Zardari . Some analysts predicted the conviction would plunge Pakistan into crisis , perhaps even spark another military coup . But on a five-day visit to the United Kingdom , Gilani remained confidant and defiant as ever about stepping down , saying that only parliament had the right to force him from office . `` If I 'm disqualified , notified by the speaker , then yes I have to , '' he said about leaving his job . Pakistan 's Supreme Court issued a detailed verdict Tuesday that made it clear it held Gilani in contempt of court for defying the highest judiciary in the land . Gilani defended himself just as strongly as he defended Pakistan and the course it has taken in battling terrorism . `` Whatever I have done is according to the constitution , '' he said . `` It is not on any moral turpitude or financial corruption . '' He said information about the most wanted terror suspects is shared with Washington . In the case of bin Laden , Gillani said Pakistan was not aware of the al Qaeda mastermind 's residence in Abbottabad . `` That was intelligence failure of the whole world . It was not just an intelligence failure of Pakistan , '' he said . Pakistanis , of all people , know the consequences of terrorists on their soil , he said . However , Clinton said this week that the United States believed Ayman al-Zawahiri was hiding in Pakistan . Al-Zawahiri inherited the al Qaeda leadership after the death of bin Laden , who spent years on the lam in Pakistan , fleeing from safe house to safe house , according to one of his widows . Clinton also touted the Rewards for Justice program , aimed at obtaining information that could help convict suspected terrorists . Rewards go as high as $ 25 million for information on al-Zawahiri and $ 10 million for information about Hafiz Mohammad Saeed , a Pakistani man wanted by Indian authorities in connection with the 2008 assault on Mumbai , India , that killed 166 people . Asked why Saeed remains a free man , Gilani said Pakistan was still `` waiting for some concrete sort of information and evidence '' that could be used against him in court .
