Khan started his career as a worker of
MQM and its student wing
APMSO. In 1992, because of having ideological differences with MQM founder
Altaf Hussain, Khan alongside
Afaq Ahmed co-founded
Muhajir Qaumi Movement – Haqiqi, a rival faction of much larger of then Muhajir Qaumi Movement which was later renamed to
Muttahida Qaumi Movement as its first
secretary general. In 2011, after suffering a long political survival as chief of MQM-H, he announced to rejoin MQM after seeking pardon from MQM founder Altaf Hussain because of his political insurgency against him in 1990s. In August 2016, after the controversial speeches of MQM founder Altaf Hussain, he alongside
Farooq Sattar and other Pakistan-based leaders of MQM distances themselves from this scenario and Sattar announced formation of
MQM Pakistan splitting away from its MQM's London based leadership for which Khan was appointed as its senior deputy convenor and core committee member. In February 2018, after having differences with Sattar over the allocations of party tickets for
2018 Pakistani Senate election, MQM-P further divided into Farooq MQM-Pakistan (PIB faction) led by Sattar and MQM-Pakistan (Bahadurabad) factions led by Khan whose
convenor later became
Khalid Maqbool Siddiqui. ==References==
