Kulsoom was placed on life support earlier in the day as her health deteriorated, Geo News reported.
She was elected from Lahore's NA-120 constituency in a by-election after her husband was disqualified from the seat by the Supreme Court last year but left for Britain even before she could start campaigning.
Born in 1950 in Lahore to a Kashmiri family, Kulsoom attended Islamia College and graduated from the Forman Christian College in Lahore. She received a Master's degree in Urdu from Punjab University in 1970.
