The Pakistan Tehreek-e-Insaf (PTI) has begun its long march towards Islamabad from Khyber Pakhtunkhwa’s Lakki Marwat after talks with the federal government failed to break the deadlock.KP Chief Minister Sohail Afridi set off from Lakki Marwat’s Gandi Chowk, saying he would announce his next course of action on Thursday, October 8, when the party’s convoy reaches Khairabad. The caravan has camped in Karak tonight, he announced later.Meanwhile, former KP CM Ali Amin Gandapur returned to his residence after the Yarik toll plaza was closed.Gandapur was scheduled to reach Gandi Chowk to join the long march, but turned back after the toll plaza was blocked with containers. He said he would not violate the law or resort to unlawful measures.PTI and a delegation from the government and PPP held three rounds of talks but on Sunday morning, they finally broke down, with Interior Minister Mohsin Naqvi clarifying that “talks have collapsed” and that the KP CM was behind their sabotage.Moreover, PTI Secretary General Salman Akram Raja claimed that the primary reason for the failure of overnight talks was the federal government’s insistence that all anti-terrorism actions it unilaterally initiated in Khyber Pakhtunkhwa must be owned by the provincial government.Party workers from Bannu, Lakki Marwat, Dera Ismail Khan and surrounding districts had gathered in Lakki Marwat ahead of the march. A heavy police contingent was also deployed in the area for security.Afridi had travelled from Peshawar to Lakki Marwat to lead the march, accompanied by PTI leaders including Junaid Akbar.The convoy will camp near Karak on Sunday night before participants from Karak join it on Monday. The march will then move towards Kohat, Peshawar and Charsadda over the following days.
