NAWAZ Sharif has by now mastered the knack of creating the most unlikely political hurdles for himself. Shortly after celebrating a year in office this month,where he boasted of uniting all the parties in Parliament and forming a government of national consensus, Sharif received a jolt last week when the Awami National Party (ANP) walked out of the alliance with one federal minister and three provincial ministers in the NWFP resigning from the coalition government. The ANP took this extreme step because Sharif refused to abide by a verbal agreement to rename NWFP and call it Pakhtoonkhwa.
