In Balochistan assembly, PML-N and its allies had a clear majority and they were ruling the province since June 2013. Nawab Sanaullah Zehri from PML-N was Chief Minister (CM) of Balochistan when the first sun of 2018 rose.
However, the next day members of his own party revolted and presented a no-confidence motion against him. Zehri had to resign a week later to avoid no-confidence motion and a new CM from the same coalition assumed charge. Central command of PML-N lost control over its members in Balochistan and this took many political pundits by surprise.
How come a political party who is ruling Pakistan can crumble overnights? The answer lies in the fact that in Balochistan the individual candidates matter and not the political parties.
