After the election of Nawaz Sharif in 1990 , the ANP again formed a coalition with former rivals PML . This alliance proved longer lasting , surviving till 1998 when it collapsed over differences over the building of Kalabagh Dam and renaming the province NWFP to Pakhtunkhwa . It won six seats in the National Assembly in the 1990 elections . In the 1993 national elections , the party won three seats in the National Assembly . It then joined the Grand Democratic Alliance , campaigning against the Sharif government 's policies . After Nawaz Sharif 's overthrow by Pervez Musharraf , the party stayed an active member of the Alliance for Restoration of Democracy , until the 2001 September 11 attacks in the United States , when it left the alliance over supporting NATO 's ouster of the Taliban government . The party 's reputation was damaged in this period following the arrest of former Federal Minister and senior party leader Azam Khan Hoti
