ISLAMABAD: Pakistan Tehreek-e-Insaf (PTI) Chairman Imran Khan Thursday warned that his party will not tolerate any delay in election process and said the election Commission of Pakistan (ECP) was duty-bound to complete process of delimitation of constituencies as soon as possible. "Governance chaos exists because of political vacuum in Pakistan today," Imran said in a tweet. He said early elections are the only solution to it and that PTI would not tolerate any delay in electoral process for any lame excuse. According to PTI media department, Imran has asked the party legislators to raise their voice strongly for merger of Fata with Khyber Pakhtunkhwa and decided to adopt a tougher line on the issue.
