• PTI has yet to announce candidate for Senate deputy chairman slot • Imran apprised of digital media advertising policy ISLAMABAD: Prime Minister Imran Khan on Monday said government senators are being approached to gain their support for the opposition’s candidate in the upcoming election for Senate chairman. On the other hand, ruling Pakistan Tehreek-i-Insaf (PTI) has so far not announced its candidate for the office of deputy chairman, keeping the slot open and placing itself in a better bargaining position to ensure support of its allies and independent candidates. Presiding over a meeting of his spokespersons, the prime minister vowed to win the chairman’s post despite opposition’s majority in the upper house.
