ISLAMABAD Alleging provincial government for pre poll rigging in NA-55, Chairman Pakistan Tehrik-e-Insaf Imran Khan, lambasted PML-N for using state machinery for election purposes in Rawalpindi. Addressing a news conference at the PTI Secretariat, Imran said closure of main arteries of the city prior to the arrival of PML-N rally led by its Chief Nawaz Sharif and refusal to allow PTI candidate to hold the public gathering were the worst example of the pre-poll rigging. PTI was apprised of the decision just three hours before the scheduled time which spoke volumes regarding PML-Ns respect for democracy, he said. He vowed that PTI would move Apex court against the undemocratic practice on part of the PML-N. He said that PTI was going to write a letter to Election Commission, in which we have briefly highlighted all the mal-practices committed in the by-election held across the country. He alleged that the city administration following the directions of the provincial government prohibited PTI to hold final procession of campaign for its candidate. All the roads leading to the Allied Hospitals, including Benazir Bhutto Hospital, Holy Family Hospital and District Headquarters Hospital were closed by the city administration early in the morning due to the visit of Nawaz Sharif in the constituency was an undemocratic practice. He said that on one part Nawaz Sharif was supporting President Zardari in the name of democracy, while on other he was causing hurdles in the campaign of other contesting candidates in NA-55, which was the worst example of dictatorship. He alleged that the current election was not free and fair, first the provincial government tried to put off the election in NA-55 and now they it is being rigged by using state machinery. He said that the PML-N workers ripped PTI candidates posters and we had solid proof of that.
