Amid stringent security in the provincial capital, the Balochistan assembly on Saturday morning voted to elect PML-Q's Mir Abdul Quddus Bizenjo as the new leader of the house in Quetta.

A political crisis developed in Balochistan following the no-confidence motion, with efforts stepped up by the PML-N, which has a government both in the centre and province, to defuse the situation. The crisis was averted on January 9 after Zehri tendered his resignation to Governor Muhammad Khan Achakzai minutes before the no-confidence motion against him.
