Pakistan's Interior Minister Rana Sanaullah has said that PML-N supremo Nawaz Sharif will return from London as soon as the electoral preparations for the general elections begin. He also made it clear that elections in the politically crucial Punjab province will not be held on May 14 despite the Supreme Court's order and "all-out efforts" of the opposition Pakistan Tehreek-e-Insaf (PTI) led by former prime minister Imran Khan. Former prime minister Nawaz Sharif, who is currently based in London, will return and supervise Pakistan Muslim League-Nawaz (PML-N) party's electoral campaign, Geo News quoted the senior party leader as saying.
