Former premier Imran Khan on Wednesday asked the institutions that if they were neutral what was stopping them from holding "free and fair elections".

"In the press conference, it was said that we are neutral and apolitical. My question is that if you have decided to be neutral then what is stopping you from fair and free elections? Let the nation decide," he said.

Addressing participants of his party's long march in Ghakkar, Imran said he wanted answers to some questions — who killed journalist Arshad Sharif, who inflicted torture on Azam Swati, who was threatening journalists in the country and who had imposed thieves over Pakistan.

"Also tell us, who did US Ambassador address in the cipher," he added.
