Abdul Qudoos Bezenjo, former deputy speaker of the provincial assembly and member of the opposition Pakistan Muslim League-Q (PML-Q) party, was sworn in as third chief minister in four years in the restive southwestern province.
Resource-rich Baluchistan is plagued by violence, perpetrated by both terrorists and nationalist insurgents fighting to keep a greater share of the revenues from gas and minerals in the province. Security has improved in recent years, though terrorists still carry out attacks.
The province also forms an important leg of the $57 billion China-Pakistan Economic Corridor of energy and infrastructure projects that China hopes to build as part of its belt and road initiative.
Bezenjo's ascent to power follows weeks of political infighting which saw provincial lawmakers from the ruling PML-N party rebel to help the opposition call for a vote of no confidence in PML-N's Nawab Sanaullah Zehri, prompting him to resign in a bitter blow to his party.
The political crisis had been intensified by speculation, widely circulated in media, that elements of Pakistan's powerful military were behind efforts to destabilise the region and possibly dissolve the assembly ahead of the senate elections due around March, and the general elections in mid-2018.
The military, which has ruled Pakistan for about half its history since independence in 1947, denies meddling in civilian politics.
Bezenjo's election is seen hurting PML-N's chances at the nationwide senate elections, with analysts saying the ruling party is now expected to get fewer senators from Baluchistan. In 2015, the vote for members of the upper house Senate was done through secret ballots of provincial lawmakers.
