PTI must give the final blow to the stumbling wall and immediately ask for to bring back Nawaz Sharif and Maryam Nawaz through Interpol. These miscreants are big time dramas and they will manipulate to procrastinate their arrest. PTI must not wait for their voluntary surrender because these criminals will definitely impede the process and would try to skim every opportunity out of stretch. PTI's demand will put forth pressure over the government and hence the due steps will be taken sooner than later.
