LAHORE The formation of an alliance led by Pakistan Tehrik-i-Insaaf Chairman Imran Khan has been delayed because a common agenda is difficult to evolve in the rapidly changing political situation in the country, a senior leader of the party said here on Saturday. The partys central leaders are due to meet in Islamabad today to review the situation and work out the PTIs future course of action. Because of the rapidly changing situation the process for formation of an alliance has been slowed down, the leader said. He said parties like PPP, PML-N, PML-Q, MQM, ANP and JUI (F) which were or had been in the power at different times had no room in the proposed alliance. Nationalist parties of smaller provinces will be taken on board, the PTI leader said. In response to a question, he said the government had failed to deliver and thus new leadership should be brought to the fore through fresh elections. But he hastened to add that fresh elections would serve no purpose unless the electoral lists were updated in accordance with Nadra cards. In his opinion, after striking down some 37 million bogus voters, as already detected by the Election Commission, it should not take the government long to update the electoral rolls on the basis of Nadra records. Then, he said, elections should be held in 90 days. Answering a question, the PTI leader said that Sundays central executive meeting would also discuss the situation that arose after the killing of Osama Bin Laden in Abbottabad and the cooperation between PPP and PML-Q, which was inconceivable until recently.
