sentences:  BSO Mengal, led by Nazeer Baloch, was formed in the early 2000s.Though it subscribes to the radical nationalist ideology of Balochistan's secession from Pakistan, it has affiliated itself with the mainstream Balochistan National Party (Mengal) (BNP–M), which is the largest opposition party in the Provincial Assembly of Balochistan.The group has gathered enough support from the student body since its split from the united BSO and demands "total autonomy" for Balochistan.
