Lahore: Punjab Chief Minister Shahbaz Sharif on Friday termed the Shimla Agreement signed by India and Pakistan after the 1971 war as a "big mistake" as it hurt the Kashmiri "freedom struggle". "The Shimla agreement was a big mistake (on the part of Islamabad) as it dampened the spirit of the Kashmiris fighting for their freedom and hurt their movement," he told a conference here. Shahbaz Sharif is the brother of Prime Minister Nawaz Sharif. Sharif's statement evoked sharp criticism from the Pakistan Peoples Party (PPP), whose then Chairman and Prime Minister Zulfikar Ali Bhutto and his Indian counterpart Indra Gandhi signed the pact in 1972. "Someone should teach the CM Punjab what foreign policy is. He can't possibly think mimicking SZAB (Shaheed Zulfikar Ali Bhutto) makes him a statesman," tweeted PPP Chairperson Bilawal Bhutto Zardari.
