His election as the first-ever Senate chairman from Balochistan marked the day's second historic moment. The first had been the swearing in of Senator Krishna Kohli earlier in the day, Dawn news reported.
Polling had taken place via a secret ballot. The counting was held shortly after the final vote was cast, with a nominee of each bloc overseeing the process.
Sanjrani had been backed by the joint opposition, including the Pakistan Peoples Party (PPP), Muttahida Qaumi Movement-Pakistan (MQM-P), Pakistan Tehreek-i-Insaf (PTI) and independents from Balochistan and the Federally Administered Tribal Areas (FATA).
